Even while the primitive rule was observed the mendicants could easily procure what of the necessaries of food and shelter and clothing they required; the jungle gave them all the shelter they needed, though it exposed them to frequent perils of being poisoned by snake-bites, and devoured by beasts. The rains put an end periodically to their peregrinations, and gathered the twos and threes who had been associating together into common retreat in the viharas. These originally were intended to be only temporary shelters from the annual floods, but as by degrees the system extended into distant regions, they became permanent institutions, each one a centre of influence in its own territory, like the abbeys in the original dioceses of mediæval Europe. Life in a Buddhist vihara two thousand years ago must however have been very different from life in a monastic establishment in the middle ages. Labour, as we have seen, of no kind was allowed, either among them or for them. “A monk who digs the earth or causes it to be dug is liable to punishment.”[287] Scant time was allowed for sleep, and when there were no books to read or transcribe, the studies or literary occupations of the West were out of the question. All the intellectual energies were claimed for the repetition of such sacred works as they knew, and for the committing to memory of others which they had only acquired. Examination of self, meditation on the five principal themes which occupied the place of prayer or devotion in their system, was expected to absorb the most of the day. Notwithstanding its intervals of instruction and discussion, it must have been a very vacant life indeed, lacking entirely the worship, and most of the duties, which rendered monastic life in Christendom, if not always profitable, at least supportable. Two outstanding features of it, however, compare very favourably with some forms of the ascetic life both in India and Europe. In the Buddhist Sanghas would be witnessed neither the slovenliness nor the dirtiness which has often been associated with the life of those who have renounced the world and have professed to despise its pleasant things. Around them, “Besmeared with mud and ashes, crouching foul, In rags of dead men, wrapped about their loins,”[288]
