[1] 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.
[18][19][20] In traditional Theravada communities, a non-Buddhist becomes a Buddhist lay disciple by repeating the ancient formulas for the Three Refuges and the Five Precepts in response to the formal administrations of a monk[21] or by himself in himself or in front of a Cetiya or an image of the Buddha.
[22][23][24][25][26] Newborns of Buddhist parents are traditionally initiated by being brought on their first outing to a temple on a full-moon or festival day where they are presented to the Triple Gem.
[27][28] The disciple hoping to receive the precepts first pays respects to the six directions, which represent their parents, teacher, husband or wife, friends, religious master and employees (traditionally servants).
The monk will ask a series of questions that ensure the practitioner has not committed grave offenses and is both physically and mentally fit to receive the precepts.
The monastic explains the benefits of the precepts as well as the negative consequences of breaking them, and asks if the disciple is prepared to accept them and remain dedicated to the Triple Gem.
Traditionally, in India, upāsakas wore white robes, representing a level of renunciation between lay people and monastics.
[30] This practice can still be found in contemporary Theravadin temples, especially during the occasion when a non-Buddhist converts to Buddhism or when one is observing the Eight Precepts on an uposatha day.
[31] In the Chinese tradition, both upāsakas and upāsikās are permitted to wear robes for temple ceremonies and retreats, as well as home practice.
Upāsakas and upāsikās wear long sleeved black robes called haiqing (海青), symbolic of their refuge in the Triple Jewel.
Unlike monastics, they are not permitted to regularly wear robes outside functions other than temple activities or Buddhist disciplines.
