Dhutanga (Pali dhutanga "renunciation", known in Thai as "Thudong") is a group of thirteen austerities or ascetic practices most commonly observed by the practitioners of the Thai Forest Tradition of Theravada Buddhism.
4. House-to-house-seeker's Practice (sapadanik'anga) — not omitting any house while going for alms; not choosing only to go to rich households or those selected for some other reason as relations, etc.
5. One-sessioner's practice (ekasanik'anga) — eating one meal a day and refusing other food offered before midday. (Those Gone Forth may not, unless ill, partake of food from midday until dawn the next day.)
11. Charnel-ground-dweller's Practice (susanik'anga) — living in or nearby a charnel-field, graveyard or cremation ground (In ancient India there would have been abandoned and unburied corpses as well as some partially cremated corpses in such places.)
