In Indian religions and society, an acharya (Sanskrit: à ¤Âà ¤Âà ¤¾à ¤°à ¥Âà ¤¯, IAST: ; Pali: ÃÂcariya) is a religious teacher in Hinduism and Buddhism and a spiritual guide to Hindus and Buddhists. The designation has different meanings in Hinduism, Buddhism and secular contexts.
Acharya is sometimes used to address an expert teacher or a scholar in any discipline, e.g.: Bhaskaracharya, the expert mathematician.
The Sanskrit phrase ÃÂcÃÂraá¹ grahÃÂyati ÃÂcÃÂraá¹ dadÃÂti iti vàmeans Acharya (or teacher) is the one who teaches good conduct to one's students. A female teacher is called an achÃÂryÃÂ, and a male teacher's wife is called an achÃÂryÃÂni
The term <nowiki/>'Acharya<nowiki/>' has numerous definitions. Hinduism frequently uses the terms "acharya" and "guru" interchangeably. According to the Dharma Shastras, acharya is the one who imparts knowledge of the entire Veda to a student and performs upanayana sanskar.
According to Nirukta, an ancillary discipline associated with the Vedas, an acharya is an individual who imparts knowledge to a student, collects wealth from the student, and helps pupils understand behaviour based on moral norms.
According to Manusmriti, the individual who, having initiated a pupil, teaches him the Veda along with the ritualistic and esoteric treatisesâÂÂhim they call, âÂÂÃÂcÃÂrya,â âÂÂPreceptorâÂÂâÂÂ(140).
Other authors' definitions:
In Buddhism, an ÃÂcÃÂrya (Pali: ÃÂcariya) is a senior teacher or master. In Theravada it is sometimes used as a title of address for Buddhist monks who have passed ten vassas. In Thai, the term is ajahn.
In Vajrayana Buddhism, tantric masters are known as vajrÃÂcÃÂryas (Tibetan: dorje lopön; Chinese: éÂÂÃ¥ÂÂé¿éÂÂ梨, pinyin: jëngÃÂng ÃÂshélÃÂ, romanji. kongà  ajari). In Chinese Buddhism, this term is also sometimes alternatively translated as jingang shangshi (Chinese: éÂÂÃ¥ÂÂä¸Â師; pinyin: JëngÃÂng Shàngshë, lit: "Vajra Superior Master") in the context of certain rituals.
In Jainism, an acharya is the highest leader of a Jain order. Acharya is one of the Pañca-Parameá¹£á¹Âhi (five supreme beings) and thus worthy of worship. They are the final authority in the monastic order and have the authority to ordain new monks and nuns. They also have the authority to consecrate new idols, though they occasionally appoint scholars to carry out this duty.
An acharya, like any other Jain monk, is expected to wander except for the Chaturmas. Bhaá¹Âá¹ÂÃÂrakas, who head institutions, are technically junior monks, and thus permitted to stay in the same place.
In Sanskrit institutions, acharya is a post-graduate degree equivalent to Master of Arts in the Anglophone world. The equivalent of a PhD is vidyÃÂvÃÂridhi.
