 During the early period of Indian thought, time (kaala) baffled the Indian thinkers to such an extent that they came to look upon it not only as the cause of the universe but also as an all-pervading principle which governs everything in it.(1) But as speculation advanced, time came to be considered one of the causes which determines the course of natural phenomena. Thus, a later Jaina scholiast, 'Silaa.nka, attempting to explain the nonabsolutism in Jaina thought, maintained that time can be recognized as one of the causal factors in the evclution of nature, because it is found that certain events like the flowering of trees, etc., occur at certain times only, not all the time.(2) In the thought of the Upani.sads, with its emphasis on permanence and eternity and the resulting denial of change and causation as being illusory, the problem of causation received scant attention.

But in early Buddhism, where there is a denial of permanence, the conceptions of change and causality, and, hence, of time, occupied prominent places. Causality (Paali, Pa.ticcasamuppaada; Skt., pratiityasamutpaada) is the central philosophy of early Buddhism. With the insight he gained as he sat contemplating under the bodhi tree on the bank of the river Nera~njaraa, the Buddha realized that everything in this world of experience is causally produced,

It was this insight that enabled him to eliminate all the doubts (karikhaa) he had entertained regarding the nature of existence.(3) Thus, in early Buddhism, the recognition of the fact that everything is impermanent (anicca), conditioned (sa.nkhata) , and causally produced (pa.ticcasamuppanna) , along with the denial of anything permanent (nicca) or eternal (dhuva, sassata) red to fruitful speculation regarding time. But it must be emphasized that during this early period of Buddhist thought whatever reflections there were on the problem of time were invariably connected with speculation on the nature of things which are temporal (kaalika). Let us begin with the Buddha's conception of the universe. Unlike his later Mahaayaana disciples who maintained that them is no beginning (anavaraagra) of the world process (sa.msaara),(4) the Buddha insisted that the beginning is totally inconceivable (anamatagga) .(5)


Although the beginning is inconceivable, yet it is possible to see periods of evolution (viva.t.ta) and dissolution (sa.mva.t.ta) following one another.(6) These periods are reckoned in terms of aeons (kappa), each of which is said to be of such immense duration that it can only be illustrated by means of similes, and these became very popular in Indian thought later on. One such simile is as follows: "If there were to be a great mountain, one league in width, one league in length and one league in height, a solid mass without chasms or clefts, and a man at the end of every hundred years, were to strike it once each time with a silken cloth, that mountain will sooner be done away with than would an p.182 aeon"(7) This passage, while emphasizing the immensity of time, also shows aeon. that we can observe events only and use processes based on these events to I measure time.(8)

Thus we derive time from events which are in time (kaalika), but not vice versa.(9) The processes of evolution and dissolution are said to take place in accordance with the causal principle which is stated as: "When this exists, that exists or comes to be; on the arising of this, that arises. When this does not exist, that does not exist or come to be; on the cessation of this, that ceases."(10) Since it has been pointed out that "there is a profound connection between the reality of time and the existence of an incalculable element in the universe,"(11) let us pause to consider the nature of the causal principle stated in the preceding formula. This causal principle was presented by the Buddha in the background of several theories, one of which was popular in the early Upani.sadic tradition. In the early Buddhist texts, this is referred to as the theory of self-causation (saya.mkata-(vaada))(12) and was based on the belief in a self (attan) considered to be the essence of everything (sabba.m) . Thus, "everything exists" (Paali, sabba.m atthi; Skt. sarvam asti) (13) means that this essence of everything exists. This leads to the view that the consequence preexists in the cause, the future in the present.

Such a strictly determined causal principle would also mean that we can, by examining the present, predict with absolute certainty what will happen in the future, for the future is merely the hidden present. For this reason temporality becomes a mere illusion. The Buddha's theory of causality differs from this in that it is not a form of strict determinism of this sort. The very use of the term 'when' (and this idea is expressed by the use of the locative absolute construction in Paali) , which in this context is equivalent to the conditional particle 'if', should be sufficient to show that the future events cannot be predicted with absolute certainty. For this reason, we find that none of the extrasensory perceptions recognized in early Buddhism refer to the future. As is well known, omniscience (sabba~n~nutaa), as later understood, was not claimed by the Buddha. We come across only two instances when the Buddha made any kind of prediction into the future with much certainty.


One is the prediction that a 'stream entrant' (sotaapanna) is certain (niyata) to attain enlightenment (sambodhiparaayana),(14) and the other is that a person who has eliminated craving and thus attained enlightenment will not be reborn ( jaati, nƒpara.m itthattaaya).(15) Both these could be considered knowledge based on inductive inference (anvaye Depending on such inductive inferences the Buddha recognized the future validity of the causal principle. This prompted him to make such declarations as: "Whether the Tathaagatas were to arise in this world or were not to arise, this causal status, this causal pattern, this conditionality remains."(17) If this causal pattern is said to exist p.183 always in this world, and if "perceiving the dhamma means perceiving causality (Pa.tccasamuppaada),"(18) then it is possible to say that his teachings will be valid at all times.

It is only in this sense that the teaching (dhamma) was described as being timeless (akaalika) .(19) On the basis of this theory of causality, it is possible to define the three periods of time, past, present, and future, in the following manner: the past is the determined (=bhuuta); the present is the moment of becoming (=bhava); and the future is the as yet undetermined (=bhavya).(20) Thus, using the terminology of Whitrow on the problem of time, it is possible to say that according to Buddhism, "the future is hidden from us--not in the present, but in the future."(21) Time is the mediator between the past and the present. Hence for that which is born (jaatassa), death is a matter of time. This may be the idea behind the use of the phrases kaala.m karoti(22) (literally, "he does his time," "is fulfilling his time"), which means dying, and kaala.m ka^nkhati(23) (literally, "awaiting time"), that is, awaiting death. For this reason, time assumes the position of Maara, the personification of death.

The famous quatrain in the Jaataka runs: Time consumes all beings including oneself; the being who consumes time, cooks the cooker of beings.(24) Although time is supposed to overwhelm ordinary human beings, yet the one who has attained enlightenment is able to bring time under his control. Just as he overwhelms Maara, the evil one, even so does he overcome time. He is said to overcome time, not because he attains to a state of permanent existence (as it wad advocated in Mahaayana),(25) but because of two important reasons. First, with the complete eradication of craving and attachment, he no longer has any longing for existence or anything associated with it Hence, dying or 'fulfilling time' (kaalakiriyaa) never worries him, as it does the ordinary man. Secondly, he has put an end to continued becoming (bhava). Thus, immortality (Paali, amata; Skt. a.mrta) in early Buddhism becomes a synonym of no-rebirth (a-punabbhava).(26) He who has overcome the process of becoming also overcomes time, because there is no time apart from the process of becoming.


As pointed out by Whitrow, "... the idea that time is ultimate and irreducible does not commit us to the unnecessary hypothesis that it is absolute, for moments do not exist in their own right but are mere classes of co-existent events."(27) It was mentioned that during the pre-Buddhist period there was a theory which upheld that "everything exists." The foundation of this theory seems to be the view that an event can never cease to be an event.(28) Because of the popularity this theory enjoyed during this period, the Buddha seems to have p.184 taken much trouble to refute it. In addition to the argument from experience that be adduced to refute this theory, the Buddha also pointed out that it was the result of a linguistic fallacy.(29) His criticism runs thus: Monks, there are these three linguistic conventions or usages of words or terms which are distinct, have been distinct in the past, are distinct at present and will be distinct in the future and which are not ignored by the recluses and brahmans who are wise.

Which three? Whatever form (ruupa) there has been, which has ceased to be, which is past and has changed is called, reckoned or termed "has been" (ahosi); it is not reckoned as "it exists" (atthi) nor as "it will be" (bhavissati). (The same is said about the other four aggregates--sensation, perception, dispositions and consciousness.)... Whatever form is not arisen, not come to be, is called, reckoned or termed is "it will be" (bhavissati) and is not reckoned as "it exists" or as "it has been." ...Whatever form has become and has manifested itself is called, reckoned or termed as "it exists" (atthi) and is not reckoned as "it has been" or as "it will be."(30)

It is very clear from this passage that the theory according to which the past and the future exist in the present or even the view that a thing exists during the past, the present, and the future an the results of unwarranted interpretation of linguistic usage. Here the temporal copulas "was," "is now," or "will in propositions which assert temporal relations between events are being confused with the timeless copulas of logic. One of the arguments against the reality of time seems to be based on the view that it is not an object of the five types of sense experience. Hence it is nothing but a mysterious illusion of the intellect.(31) For early Buddhism, which not only recognized six senses but also held that the sixth sense (that is, the mind) could be developed to perceive, with the help of memory, a long period of one's past history, time was an important ingredient of experience.(32)

As if rejecting the theory of atomic moments of time, which is recognized to be a logical abstraction,(33) the Buddha is represented as saying: "This physical body made up of the four primary existents is seen to exist for one, two, three, four, five,ten, twenty, thirty, forty, fifty, hundred or more years. That which is called the mind, thought or consciousness arises as one thing and ceases as another whether by night or by day."(34) This is a clear recognition of the two types of experience that we have. One is the experience of things which endure for some finite segment of time, and the other is the experience of momentary things. The latter experience is illustrated by the simile of the flowing river.


According to the description in the early Buddhist texts, "there is no moment, no inkling, no particle of time that the river stops flowing."(35) These two types of experience of time can be compared to the experiences one has of the movement of the two hands of the clock, the hour hand and the second hand.(36) It is important to note that early Buddhism never reduced the experience of the former to the experience of the latter, although logical abstraction can always lead to such a hypothesis. In fact, a reduction p.185 form of experience into further indivisible moments (Paali,; Skt. was carried out during the period of scholasticism, and such a theory is conspicuous by its absence in the early discourses. Therefore, during the early period, although there were statements which could be interpreted to mean a theory of momentariness, the most dominant view was the one which recognized a finite segment of time as constituting our immediate experience...

The recognition of this finite segment of time means that according to early Buddhism there is a duration of temporal experience with a certain unification of perspective. For this reason, unlike in the cases where a theory of moments dominated, (37) early Buddhism considered both time and causation as parts of our experience, not as mere inferences based primarily on the succession of momentary ideas. Thus, it is possible to maintain that early Buddhism presents us with an empiricist analysis of time. With regard to the problem of time, early Buddhism seems to have followed the middle path, so famous in the history of Buddhist thought.

It appears as if it considered absolute time as an extreme and an unnecessary hypothesis. The other extreme is the consideration of time as a mysterious illusion of the intellect. Avoiding both these extremes, the Buddha seems to have considered tune as an essential feature of the universe and the experience of it. With the development of scholasticism after the passing away of the Buddha, this empiricist philosophy of time and temporality changed completely. Unbridled speculation during the period of the Abhidharma led to the development of many theories which are more metaphysical than empirical.


In his desire to eliminate the pre-Buddhist conception of an eternal and immutable self (attan), the Buddha adopted the analytical method (vibhajjavaada) of reducing things to their components. Thus the human personality was analyzed sometimes into five aggregates (Paali, khandha; Skt. skandha) and at other times into six elements (dhaatu). Yet all these aggregates, as well as the elements, were the contents of experience, not of pure logical analysis. But with the development of scholasticism, this analytical approach was carried to its logical conclusion, and the result was the emergence not only of a theory of atoms ( but also a theory of moments (, spatial analysis giving rise to temporal atomicity.(38) The development of these two theories occasioned several other doctrines which are not compatible with the basic teachings of the Buddha.

One of the immediate results of the analysis of time into atomic units or chronons was the view that time is fleeting or flowing from the future into the present and from the present into the past. Thus, in the commentarial literature, we come across expressions such as gacchante gacchante kaale meaning "as time passed by" or "with the passage of time."(39) All these developments were summarized by Buddhaghosa in the Atthasaalinii, his commentary on the Dhammasa.ngani, where he refers to the three p.186 varieties of the present (paccuppanna).(40) The first is the pretensive present (addhaa paccuppanna) or the finite segment of time constituting our immediate experience.

This is said to be the kind of present recognized in the discourses (sutta). The second is the flowing or the continuing present (santati paccuppanna) , which was then accepted in the commentarial tradition (a.t.thakathaa). The third is the momentary present ( paccuppanna), which is not identified with any tradition. Yet it was the conception mentioned last which dominated the scholastic tradition. Buddhaghosa's commentary on the Vibha^nga, the second book of the Abhidhamma Pi.taka, in introducing the theory of moments, says that it is a doctrine peculiar to the Abhidhamma and not to the Suttanta. According to this, ruupa (matter or form) is classified as past, future, or present (atiitaanaaga-tapaccuppanna) in the Suttanta and this division is made an the basis of becoming (bhavena paricchinna) . In the Abhidhamma, however, the division is made on the basis of moments (kha.nena paricchinna).(41)

Am ddha.jpg

These are different versions of the theory of moments. The Sarvaastivaadins recognized four moments, the nascent (jaati), the static (sthiti), the decaying (jaraa), and the cessant (naa'sa).(42) Post-Buddhaghosan Theravaada recognized three: the nascent (uppaada), the static (.thiti), and the cessant (bha^nga) .(43) The Sautraantikas differed from all of them in accepting two moments only, the nascent (utpaada) and cessant (vyaya), and rejecting the static moment ( The difficulties posed by the analysis of time into atomic units are innumerable. Although a moment was considered to be the unanalyzable unit of time, it was found that a distinction had to be made between a moment of thought and a moment of matter, because, as pointed out earlier, thought changes more rapidly than physical bodies.(45) Therefore, in the Theravaada Abhidhamma it is said that during the lifetime of a single moment of matter sixteen moments of thought arise and pass away.(46)

The most difficult problem created by the theory of moments concerned the experienced continuity of temporal events. A moment was considered to be durationless, comparable to the dimensionless point of space, and hence, past, present, and future moments are utterly distinct from each other. They are discrete. To explain the problem of continuity arising as a result of the analysis of time into momentary and discrete units, the Buddhist schools offered various solutions. The most widely known and the most severely criticized of these different solutions was that proffered by the Sarvaastivaadins who insisted that underlying the succession of momentary events is the substance or 'own-nature' (dravya, svabhaava) which remains unchanged.(47) Thus, a thing (dharma) has two aspects: the characteristic ( which is temporal (kaalika, and the substance (dravya) which is eternal or p.187 timeless. The term sarvaastivaada means the "theory that everything exists" (sarvam asti) .

This everything (sarvam) was the substance of everything which, they held, exists during the three periods, past, present and future. This theory was examined by the Theravaadins in their Kathaavatthu where they make the Sarvaastivaadins admit that not only everything past, present, and future exists, but that past, present, and future themselves exist, that is, they are independently real.(48) While the basic theory of the Sarvaastivaadins was not much different from the Upani.sadic theory of "everything exists" referred to and criticized by the Buddha, there is also a significant difference. Unlike the thought of the Upani.sads which is idealistic, the Sarvaastivaada represented a school of realism and therefore, as pointed out by the Theravaadins, they upheld the independent reality not only of things, but also of time.

It is interesting to note that in support of their rejection of this theory of "everything exists" (sarvam asti), the Theravaadins are represented as quoting a discourse from the Buddha on the nature of linguistic conventions referred to earlier.(49) The school of Buddhism known as the Sautraantika rejected the Sarvaastivaada conception of substance (svabhaava) as being no different from the theory of self (atman) .(50) But the rejection of this underlying substance compelled them to the view that there is no duration whatsoever and that what appears as duration is a series of fleeting moments, like the cinematograph. This continuum of durationless instants, no doubt, is the result of logical abstraction, a theoretical construction based on the empirical data of consciousness. Unlike the Theravaadins who recognized two different types of moments, that is, a moment of thought and a moment of matter, the Sautraantikas made no such distinctions. The most important consequence of this conception of time was the theory that there are no instantaneous connections between external events and the observer.(51) Hence there is no direct perception of an object; there is inferential knowledge (anumaana) only.

Thus the Sautraantikas were popularly known for their doctrine of "representationism," that is, the inferability of the external object (bahyaarthaanumeyavaada).(52) In the Mulamadhyamakakaarika, Naagaarjuna devotes one chapter to the examination of the problem of time.(53) It is indeed a very short but extremely important chapter. There is no doubt that it was the Sarvaastivaada conception of time which drew the criticism from Naagaarjuna. The theory, as explained by Candrakiirti, recognized the existence of the substance of things during the three periods. It was argued by the realist that since substance exists, time with which it is associated also exists.(54)

It is this independent reality of time which Naagaarjuna takes up for criticism. His criticism was based on the fact that a thing (bhaava) or its substance (bhaavasvabhaava) and time (kaala) are relative to or dependent upon one another Early Buddhism, as pointed p.188 out earlier, would have stopped at this point, but Naagaarjuna did not. He employed his dialectic to demonstrate the unreality or nonexistence of time.(55) Naagaarjuna's. agrument was based on the assumption that two thing cannot be related unless they are coexistent.

Mind 420x0.jpg

Hence, if present and future are held to be contingently related to the past, then both present and future should be in the past. Otherwise they cannot be contingently related. On the other hand, present and future could not exist without being contingent on the past. Hence, according to Naagaarjuna, there is no justification for the recognition of a present and a future time.(56) The selfsame argument was used to refute the reality of the part. Past, present, and future, which were comparable to such concepts as above, below and middle (uttamaadhamamadhyama), or arising, enduring, and passing away (utpaadasthibhannga) , etc., could not thus withstand the onslaught of Naagaarjuna's dialectic.

The opponents argued that time exists because it has dimension and is measured in terms of moments, days, fortnights, months, and years.(57) Naagaarjuna pointed out that it is not possible to measure time. He maintained that nonenduring or nonstatic time cannot be measured, because it cannot be manipulated, and that an enduring or static time, although manipulatable, does not exist.(58) By way of conclusion, Naagaarjuna points out that if time exists depending on existential structure, then it cannot be obtained without such structure. But no existential structure is to be found, for he has already refuted such a structure.(59) Hence, according to him, time does not exist. Naagaarjuna claimed that his exposition of the doctrine is based on the recognition of the two truths, the conventional ( and the ultimate truth (paramaartha-satya).(60)

According to Candrakiirti, the ultimate truth is the independent (aparapratyaya) , peaceful ('santa) , without conceptual proliferation (prapa~ncaatiita) , nonconceptual (nirvikalpa), and without plurality (anekaartha).(61) Hence, Naagaarjuna's, no doubt, was a transcendentalist criticism of phenomenal reality. This would become clear from a comparison of the standpoints adopted by the two schools, early Buddhism and Maadhyamika. When early Buddhism maintained that things are relatively real, Naagaarjuna insisted that things are unreal because they are relative, the real being the transcendental. Summing up the whole discussion, I may say that (1) early Buddhism presented an empiricist and relativistic conception of time; (2) the Abhidharma scholasticism produced an absolutistic conception mainly because of its speculative approach, and (3) the Maadhyamikas, as a result of their transcendentalism, denied the reality of time.
