The earliest known texts often ask for ascetics to be in complete solitude, identifying the isolation of soul and non-soul. However, soon after Mahavira's
nirvana ascetics organized themselves into groups. A few examples of ascetics living in complete solitude are found in both
Digambara and
Śvetāmbara sects. Jain ascetics are detached from social and worldly activities; all activities are aimed at self-purification for self-realization as well as to spread the word of
Jainism. They follow established guidelines for daily worship and austerity. The monk's daily routine is broadly structured by three ideological formulae: the five great vows (
mahavrata), the eight matrices of doctrine (
pravacana-matrka), and the six obligatory actions (
avasyaka). The first two are restrictions, and the third is positively framed in what the monk is encouraged to do daily. Ascetics do not have a home or possessions. They choose austerity, avoid services such as telephones and electricity. Monks engage in activities such as meditation, seeking knowledge and acquiring self-discipline. Jain monks and advanced laypeople avoid eating after sunset, observing a vow of
ratri-bhojana-tyaga-vrata.
Digambara monks eat only once a day and do not use utensils. The
Yati of the
Śvētāmbara sect and the
Bhattaraka of the Digambara Terapanth do not wander; they usually live in temples and perform daily rituals. The monks rise before dawn, most around 5:00 a.m. but some as early as 2:00 a.m. Five
mahāvratas (Great Vows), from Mahavira's teachings, are followed by all Jain ascetics. Although Jain householders are also required to observe them, ascetics are bound more strictly. ==Ranks==
