One should not injure, subjugate, enslave, torture, or kill any animal, living being, organism, or sentient being. Just as suffering is painful to you, in the same way it is painful, disquieting and terrifying to all animals, living beings, organisms and sentient beings.
True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance… To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.
When an exalted soul realises that all sentient beings are one in relation to the Supreme – that is, that all beings are the minute parts of the One – how shall he have any more delusion and what grief will come to him?
