In Theravada Buddhism, the Pāṭimokkha is the basic code of monastic discipline, consisting of 227 rules for fully ordained monks (bhikkhus) and 311 for nuns (bhikkhuṇīs). It is contained in the Suttavibhaṅga, a division of the Vinaya Piṭaka. Pārājika The four pārājikas (lit. "defeats") are rules entailing expulsion from the sangha for life. If a monk breaks any one of the rules he is automatically "defeated" in the holy life and falls from monkhood immediately. He is not allowed to become a monk again in his lifetime. Intention is necessary in all these four cases to constitute an offence. The four parajikas for bhikkus are: Sexual intercourse: engaging in any sexual intercourse. Stealing: the robbery of anything worth more than 1/24 troy ounce of gold (as determined by local law). Killing: bringing about the death of a human being — whether by killing the person, arranging for an assassin to kill the person, inciting the person to die, or describing the advantages of death. Lying: lying to another person that one has attained a superior human state, such as claiming to be an arahant when one knows one is not, or claiming to have attained one of the jhānas when one knows one has not. The pārājikas are more specific definitions of the first four of the Five Precepts. Saṅghādisesa The thirteen saṅghādisesas are rules requiring an initial and subsequent meeting of the sangha (communal meetings). If a monk breaks any rule here he has to undergo a period of probation or discipline after which, if he shows himself to be repentant, he may be reinstated by a sangha of not less than twenty monks. Like the pārājikas, the saṅghādisesas can only come about through the monk's own intention and cannot be accidentally invoked. The thirteen saṅghādisesas for bhikkus are: Discharge of semen or getting someone to discharge your semen, except while dreaming. Lustful bodily contact with a woman, including kissing or holding hands. Making lustful remarks to a woman alluding to her genitals or sexual intercourse. Requesting sexual favors from a woman, or telling her that she would benefit spiritually from having sex with the monk. Arranging for a date, affair, or marriage between a man and woman. Building a hut without permission from the sangha, or building a hut that exceed 3 x 1.75 meters in size. Having someone else build a hut for you without permission from
