The Sangha or community of ordained Buddhist bhikkhus ("beggar" or "one who lives by alms".) and original bhikkhunis (nuns) was founded by Gautama Buddha during his lifetime over 2500 years ago. This communal monastic lifestyle grew out of the lifestyle of earlier sects of wandering ascetics, some of whom the Buddha had studied under. It was initially fairly eremitic or reclusive in nature. Bhikkhus and bhikkunis were expected to live with a minimum of possessions, which were to be voluntarily provided by the lay community. Lay followers also provided the daily food that bhikkhus required, and provided shelter for bhikkhus when they needed it.
