text: The earliest known gift of immovable property for monastic purposes ever recorded in an Indian inscription is credited to Emperor Ashoka, and it is a donation to the Ajivikas. According to Johannes Bronkhorst, this created competitive financial pressures on all traditions, including the Hindu Brahmins. This may have led to the development of viharas as shelters for monks, and evolution in the Ashrama concept to agraharas or Hindu monasteries. These shelters were normally accompanied by donation of revenue from villages nearby, who would work and support these cave residences with food and services. The Karle inscription dated to the 1st century CE donates a cave and nearby village, states Bronkhorst, "for the support of the ascetics living in the caves at Valuraka [Karle] without any distinction of sect or origin". Buddhist texts from Bengal, dated to centuries later, use the term asrama-vihara or agrahara-vihara for their monasteries.
  Buddhist viharas or monasteries may be described as a residence for monks, a centre for religious work and meditation and a centre of Buddhist learning. Reference to five kinds of dwellings (Pancha Lenani) namely, Vihara, Addayoga, Pasada, Hammiya and Guha is found in the Buddhist canonical texts as fit for monks. Of these only the Vihara (monastery) and Guha (Cave) have survived.
  At some stage of Buddhism, like other Indian religious traditions, the wandering monks of the Sangha dedicated to asceticism and the monastic life, wandered from place to place. During the rainy season (cf. vassa) they stayed in temporary shelters. In Buddhist theology relating to rebirth and merit earning, it was considered an act of merit not only to feed a monk but also to shelter him, sumptuous monasteries were created by rich lay devotees.
