A man traveling across a field encountered a tiger. He fled, the tiger after him. Coming to a precipice, he caught hold of the root of a wild vine and swung himself down over the edge. The tiger sniffed at him from above. Trembling, the man looked down to where, far below, another tiger was waiting to eat him. Only the vine sustained him. Two mice, one white and one black, little by little started to gnaw away the vine. The man saw a luscious strawberry near him. Grasping the vine with one hand, he plucked the strawberry with the other. How sweet it tasted!

To avoid causing terror to living beings, let the disciple refrain from eating meat... the food of the wise is that which is consumed by the sadhus [holymen]; it does not consist of meat... There may be some foolish people in the future who will say that I permitted meat-eating and that I partook of meat myself, but... meat-eating I have not permitted to anyone, I do not permit, I will not permit meat-eating in any form, in any manner and in any place; it is unconditionally prohibited for all.

As an elephant in the battlefield withstands arrows shot from bows all around, even so shall I endure abuse.
