Ācārāṅga Sūtra 0.8.2

Whatever different seats and couches have been told, whatever have been used by the great Hero, these resting-places are thus detailed.

He sometimes lodged in workshops, assemblingplaces, wells, or shops; sometimes in manufactories or under a shed of straw.

He sometimes lodged in travellers' halls, gardenhouses, or towns; sometimes on a burying-ground, in relinquished houses, or at the foot of a tree.

In these places was the wise Sramana for thirteen long years; he meditated day and night, exerting himself, undisturbed, strenuously.

The Venerable One, exerting himself, did not seek sleep for the sake of pleasure; he waked up himself, and slept only a little, free from desires.

Waking up again, the Venerable One lay down, exerting himself; going outside for once in a night, he walked about for an hour.

In his resting-places he sustained fearful and manifold calamities; crawling or flying animals attack him.

Bad people, the guard of the village, or lancebearers attack him; or there were domestic temptations, single women or men;

Fearful and manifold (calamities) of this and the next world; pleasant and unpleasant smells, and manifold sounds:

Always well controlled, he bore the different sorts of feelings; overcoming carelessness and pleasure, the Brahmana wandered about, speaking but little.

In the resting-places there once, in a night, the single wanderers asked him (who he was, and why he was there); as he did not answer, they treated him badly; but he persevered in his meditations, free from resentment.

(Sometimes to avoid greater troubles when asked), 'Who is there within?' he answered, 'It is I, a mendicant.' But this is the best law: silently to meditate, even if badly treated.

When a cold wind blows, in which some feel pain, then some houseless monks in the cold rain seek a place sheltered from the wind.

(Some heretical monks say), 'We shall put on more clothes; kindling wood or (well) covered, we shall be able (to bear) the very painful influence of the cold.'

But the Venerable One desired nothing of the kind; strong in control, he suffered, despising all shelter. Going outside once of a night, the Venerable One was able (to endure all hardships) in calmness.

This is the rule which has often been followed by the wise Brâhmana, the Venerable One, who is free from attachment: thus proceed (the monks). Thus I say.
