Sagrado sutra Akaranga del jainismo : Lecciones sobre liberación y rectitud. Parte 2 de 2.

The Venerated One was able to abstain from indulgence of the flesh，Sometimes in the cold season the Venerated One was meditating in the shade. In summer He exposes himself to the heat, He sits squatting in the sun. though never attacked by diseases. Having wisdom, Mahavira committed no sin Himself, nor did He induce others to do so, nor did He consent to the sins of others. He should give up all motions except his own in the thrice-threefold way. He should not lie on sprouts of grass, but inspecting the bare ground he should lie on it. He lives, forsooth, in accordance with wisdom and restraint, and walks free from desire, and with conquered sensuality. He for whom there is no bondage whatever in this world.
