Mahabharata Aswamedha Parva Chapter 46:3

Mahabharata Aswamedha Parva (Anugita Parva) Chapter 46:3 He should, again, accept only as much as he can eat and nothing more. He should not be induced to accept gifts from others, nor should he make gifts to others. Owing to the helplessness of creatures, the man of wisdom should always share with others. He should not appropriate what belongs to others, nor should he take anything without being asked. He should not, having enjoyed anything become so attached to it as to desire to have it once more. One should take only earth and water and pebbles and leaves and flowers and fruits, that are not owned by any body, as they come, when one desires to do any act. One should not live by the occupation of an artisan, nor should one covet gold. One should not hate, nor teach (one that does not seek to be taught); nor should one have any belongings. One should eat only what is consecrated by faith. One should abstain from controversies. One should follow that course of conduct which has been said to be nectarine. One should never be attached to anything, and should never enter into relations of intimacy with any creature. One should not perform, nor cause to perform, any such action as involves expectation of fruit or destruction of life or the hoarding of wealth or articles. Rejecting all objects, content with a very little, one should wander about (homeless) pursuing an equal behaviour towards all creatures mobile and immobile. One should never annoy another being; not should one be annoyed with another. He who is trusted by all creatures is regarded as the foremost of those persons that understand Emancipation. One should not think of the past, nor feel anxious about the future. One should disregard the present, biding time, with concentrated mind. One should never defile anything by eye, mind, or speech. Nor should one do anything that is wrong, openly or in secret. Withdrawing one's senses like the tortoise withdrawing its limbs, one should attenuate one's senses and mind, cultivate a thoroughly peaceful understanding, and seek to master every topic.
