Mahabharata Anushasna Parva Chapter 31:4

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 31:4 "'Yudhishthira said,—"O grandsire, O thou of great wisdom, O thou that art conversant with all branches of knowledge, I desire to hear thee discourse on topics connected with duty and righteousness. Tell me truly, O chief of Bharata's race, what the merits are of those persons that grant protection to living creatures of the four orders when these pray for protection." "'Bhishma said, "O Dharma's son of great wisdom and widespread fame, listen to this old history touching the great merit of granting protection to others when protection is humbly sought. Once on a time, a beautiful pigeon, pursued by a hawk, dropped down from the skies and sought the protection of the highly-blessed king Vrishadarbha. The pure-souled monarch, beholding the pigeon take refuge in his lap from fear, comforted him, saying, 'Be comforted, O bird; do not fear. Whence hast thou taken such great fright? What hast thou done and where hast thou done it in consequence of which thou hast lost thy senses in fear and art more dead than alive? Thy colour, beautiful bird, is such as to resemble that which adorns a fresh-blown lotus of the blue variety. Thy eyes are of the hue of the pomegranate or the Asoka flower. Do not fear. I bid thee, be comforted. When thou hast sought refuge with me, know that no one will have the courage to even think of seizing thee,—thee that hast such a protector to take care of thy person. I shall for thy sake, give up today the very kingdom of the Kasi and, if need be, my life too. Be comforted, therefore, and let no fear be thine, O pigeon. The hawk said, 'This bird has been ordained to be my food. It behoves thee not, O king, to protect him from me. I have outcoursed this bird and have got him. Verily, with great effort have I got at him at last. His flesh and blood and marrow and fat will be of great good to me. This bird will be the means of gratifying me greatly. Do not, O king, place thyself between him and me in this way. Fierce is the thirst that is afflicting me, and hunger is gnawing my bowels. Release the bird and cast him off. I am unable to bear the pains of hunger any longer. I pursued him as my prey. Behold, his body is bruised and torn by me with my wings and talons. Look, his breath has become very weak. It behoves thee not, O king, to protect him from me. In the exercise of that power which properly belongs to thee, thou art, indeed competent to interfere in protecting human beings when they are sought to be destroyed by human beings. Thou canst not, however, be admitted to have any power over a sky-ranging bird afflicted with thirst. Thy power may extend over thy enemies, thy servants, thy relatives, the disputes that take place between thy subjects. Indeed, it may extend over every part of thy dominions and over also thy own senses.
