PāṭimokkhaIn 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. 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.
NekkhammaNekkhamma (; naiṣkrāmya) is a Pāli word generally translated as "renunciation" or "the pleasure of renunciation" while also conveying more specifically "giving up the world and leading a holy life" or "freedom from lust, craving and desires." In Buddhism's Noble Eightfold Path, nekkhamma is the first practice associated with "Right Intention." In the Theravada list of ten perfections, nekkhamma is the third practice of "perfection." It involves non-attachment (detachment).
Eight preceptsIn Buddhism, the eight precepts (aṣṭāṇga-śīla or aṣṭā-sīla, aṭṭhaṅga-sīla or aṭṭha-sīla) is a list of precepts that are observed by lay Buddhists on observance days and festivals. They include general precepts such as refraining from killing, but also more specific ones, such as abstaining from cosmetics and entertainments. This tradition of keeping the eight precepts on observance days are still widely practice in all Theravadin Buddhist countries and Theravadin Buddhist communities worldwide.
UpāsakaUpāsaka (masculine) or Upāsikā (feminine) are from the Sanskrit and Pāli words for "attendant". This is the title of followers of Buddhism (or, historically, of Gautama Buddha) who are not monks, nuns, or novice monastics in a Buddhist order, and who undertake certain vows. In modern times they have a connotation of dedicated piety that is best suggested by terms such as "lay devotee" or "devout lay follower".
AdhiṭṭhānaAdhiṭṭhāna (Pali; from adhi meaning "foundational" or "beginning" plus sthā meaning "standing"; Sanskrit, अधिष्ठान) has been translated as "decision," "resolution," "self-determination," "will", "strong determination" and "resolute determination." In the late canonical literature of Theravada Buddhism, adhiṭṭhāna is one of the ten "perfections" (dasa pāramiyo), exemplified by the bodhisatta's resolve to become fully awakened.
Transfer of meritTransfer of merit (pariṇāmanā, pattidāna or pattānumodanā) is a standard part of Buddhist spiritual discipline where the practitioner's merit, resulting from good deeds, is transferred to deceased relatives, to deities, or to all sentient beings. Such transfer is done mentally, and it is believed that the recipient can often receive this merit, if they rejoice in the meritorious acts of the person transferring. In Buddhism, merit transfer is seen as a better alternative than mourning.
