Novice and Full Ordination
The ordination procedure for Buddhist monks, know, as the 'Going forth', begins with the applicant's formal request (Pabbajja) to a senior monk or bhikkhu for the novice (samanera) ordination.
On receiving permission, the applicant prepares for the ceremony by acquiring a complete set of robes and getting the help of the monks in the monastery to shave his head.
Then he approaches the senior monk and pays his respects by bowing three times and hands over the robes saying a passage prescribed for the purpose. Then he formally asks the senior monk to give him the robes, and having received them he is helped by the monks to put them on. The applicant then makes a formal request for the novice ordination. The senior monk acquiescing administers the Three Refuges and the Ten Precepts or training rules.
The Prescribed Passages
When handing over the robes:
Venerable Sir, I respectfully ask you to take this set of robes in my hand and out of compassion ordain me as a novice in order that I may be free from the cycle of existence.
Asking the senior monk for the robes:
Venerable Sir, I respectfully ask you to give me the set of robes in your hand and out of compassion ordain me as a novice in order that I may be free from the cycle of existence.
Requesting the Novice Ordination:
Venerable Sir, I respectfully ask you to ordain me as a novice in order that I may be free from the cycle of existence and attain Nibbana.
The candidate then takes refuge in the Triple Gem (Buddha, Dhamma and Sangha) and undertakes the Ten Training Rules or Precepts in Pali:
Buddham saranam gacchami
Dhammam saranam gacchami
Sangham saranam gacchami
Dutiyampi ...
Tatiyampi …
I take refuge in the Buddha
I take refuge in the Dhamma
I take refuge in the Sangha (three times)
The Ten Precepts:
1. Panatipata veramani sikkhapadam samadiyami
(I undertake to abstain from harming or taking life).
2. Adinnadanna veramani sikkhapadam samadiyami
(I undertake to abstain from taking what is not given).
3. Abrahmacariya veramani sikkhapadam samadiyami

(I undertake to abstain from using luxurious seats).
10. Jatarupa rajata patiggahana veramani sikkhapadam samadiyami
(I undertake to abstain from accepting and holding money).
Finally, as a novice, he requests the senior monk to be his Preceptor and on being accepted he receives a new name in Pali.
Upajjhayo me bhante hohi. (three times)
Venerable Sir, would you kindly be my preceptor?
Higher Ordination (Upasampada, Acceptance as a Bhikkhu)
In the Buddhist monk's code of ethics, the Vinaya, the Buddha decreed that a condition for higher ordination is that the candidate has a Preceptor. Accordingly, at the time of his novice ordination the candidate begged the senior monk to be his Preceptor; the senior monk agreed to do so, and thus the applicant has a preceptor to guide him so long as he remains a bhikkhu in the Buddha's dispensation (Sasana).
Telling the Robes and Bowl:
The Teacher (Acariya) now instructs the candidate:
Please listen to me, according to the Vinaya rules an applicant should be checked to see that he has a complete set of three robes and an alms-bowl before he can receive higher ordination as a bhikkhu:
This is your alms-bowl. (Indicates each item) This is your outer robe. This is your upper robe. This is your inner robe.
I have now ascertained that you have a complete set of robes and an alms-bowl. The Assembly will give you and your preceptor new names in order to read the "The Motion and the Three Announcements" (Kammavaca) easily and to show respect to the preceptor.
Your new name is Naga and your preceptor's name is Venerable Tissa. The Assembly of the Sangha (community of monks) will use the name Naga for the applicant and Venerable Tissa for the preceptor. These two names will be used in the course of the ceremony for this bhikkhu ordination.
Please listen to me, Naga, now is the time to instruct you on how to answer the questions that will be put to you by the Assembly. It is not, however, correct to instruct you in the middle of the Assembly - therefore, I will instruct you outside of it.
Please stand up, Naga, and go backwards with your palms together in the 'prayer posture' thereby paying respects to the Assembly of the Sangha. Then stop at a place about twenty feet from the Assembly and stand there.
Please listen attentively, Naga, now is the time for you to be honest and tell the truth. When you are back in the middle of the Assembly of the Sangha you will be questioned concerning any hindrances regarding your eligibility for higher ordination. Answer truthfully and according to the facts, do not be at a loss, do not be embarrassed. You are just to answer 'yes' if it is true or 'no' if it is not.
The questions are as follows:
1. Do you suffer from leprosy?
If you do, answer 'Yes, Venerable Sir', if you do not, answer 'No, Venerable Sir'.
2. Have you got boils?
3. Have you got eczema?
4. Have you got tuberculosis?
5. Do you get epilepsy?
6. Are you a human being?
7. Are you a man?
8. Are you a free man?
9. Are you free from government service?
10. Have you got your parents' permission to be ordained?
11. Have you a set of three robes and an almsbowl?
12. What is your name? (My name is Naga.)
13. What is your preceptor's name? (My preceptor's name is Venerable Tissa.)
I have instructed you, Naga, on how to answer the questions that you will be asked when you are back in the Assembly. I am now going to the Assembly alone, you are to remain here and come to the Assembly only when you are called.
Requesting the Higher Ordination:
Then the senior monk returns to the assembly, bows, and says: "May the Sangha hear me. The candidate, Naga, under the Venerable Tissa, has been examined. If the Sangha is willing may he be allowed to come forward."
The senior monk says:
"Now is the time for you, Naga, to request the Sangha to ordain you a bhikkhu. Your request should be both in Pali and English".
At the command to come the novice approaches, bows three times, kneels with hands together, says.
Sangham Bhante upsampadam yacami.
Ullumpatu mam bhante Sangho anukampam upadaya.
Dutiyampi Sangham bhante...
Tatiyampi Sangham bhante...
Venerable Sir, I respectfully request the Sangha to ordain me a bhikkhu. I beg the Sangha out of compassion to lift me up from the status of a novice. (three times)
Sunatu me bhante sangho. Ayam nago ayasmato tissassa upasampadapekkho. Yadi sanghassa pattakallam. Aham nagam antarayike dhamme puccheyyam.
The Motion and the Three Announcements:
The Preceptor then invites the assembly to examine the novice in regard to the obstacles to entering the Order, saying:
"The novice Naga is an initiate whom I sponsor and he wishes to enter the monkhood before this Sangha. I invite the Sangha to examine this novice by asking the antarayikadharma of him (obstacles to entering the Order). He knows the prescribed form of the higher ordination (Upasampada) ceremony. Let us agree to conduct the ceremony with the prescribed kammavaca form (The Motion) together with the threefold announcement in order that nothing be amiss."
The candidate is then questioned in the Assembly:
Please listen carefully, Naga, now is the time for you to answer clearly, do not be at a loss, do not be embarrassed. On behalf of the Sangha I will ask you questions that will assess your eligibility for the bhikkhu ordination. You are just to answer 'Yes' or 'No' Venerable Sir.
Questions:
Do you suffer from leprosy? (No, Venerable Sir)
(All the questions are as mentioned above.)
Then the Teacher (Acariya) says:
May the Sangha hear me. Naga the pupil of Venerable Tissa is free from the Eight Obstacles. He has his robes and bowl. Naga begs admission to the Sangha. If the members of the Sangha assembled here are ready they should admit Naga to the Sangha. Venerable Tissa is his Preceptor. This is the prescribed manner. May the Sangha hear me.
Naga is the pupil of Venerable Tissa. He is free from the Eight Obstacles. He has his robes and bowl. He begs admission to the Sangha. May the Sangha admit Naga. Venerable Tissa is his Preceptor.
Let those who are agreed keep silent. If anyone does not agree let him speak out. For the second time I speak. May the Sangha hear me. (a repetition of the above) For the third time I speak. May the Sangha hear me. (a repetition of the above) Let those who are agreed keep silent. If anyone does not agree let him speak out.
The Sangha is silent, therefore Naga is admitted to the Sangha. Venerable Tissa is his Preceptor. The Sangha is agreed, therefore is silent. I too become silent.
With these words the ordination as a service of admission to the monkhood is concluded. Either immediately following this or some time later, the newly admitted monk to the Order is given instruction concerning the life of the bhikkhu.
