Sacred Books of the East, vol. 22: Gaina Sutras Part I, translated by Hermann Jacobi [1884], at sacred-texts.com
To a naked 1 monk the thought occurs: I can bear the pricking of grass, the influence of cold and heat, the stinging of flies and mosquitos; these and other various painful feelings I can sustain, but I cannot leave off the covering of the privities. Then he may cover his privities with a piece of cloth 2.
A naked monk who perseveres in this conduct, sustains repeatedly these and other various painful feelings: the grass pricks him, heat and cold attack him, flies and mosquitos sting him. A naked monk (should be) aspiring to freedom from bonds. Penance suits him. Knowing what the Revered One has declared, one should thoroughly and in all respects conform to it. (1)
A monk who has come to any of the following resolutions,--having collected food, &c., I shall give of it to other monks, and I shall eat (what they have) brought; (or) having collected food, &c., I shall give of it to other monks, but I shall not eat
[paragraph continues] (what they have) brought; (or) having collected food, &c., I shall not give of it to other monks, but I shall eat (what they have) brought; (or) having collected food, &c., I shall not give of it to other monks, nor eat (what they have) brought; (2) (or) I shall assist a fellow-ascetic with the remnants of my dinner, which is acceptable 1 and remained in the same state in which it was received 2, and I shall accept the assistance of fellow-ascetics as regards the remnants of their dinner, which is acceptable and remained in the same state in which it was received;--(that monk should keep these vows even if he should run the risk of his life) (3)--aspiring to freedom from bonds. Penance suits him. Knowing what the Revered One has declared, one should thoroughly conform to it. (4)

Thus I say. (5)
