Said Yudhishthira: “They that are pious make The Way; space is called water; the cow is food[275]; a request is poison.” [275] Babu P. C. Roy comments on this head: “The cow is the only food in this sense. The cow gives milk. The milk gives butter. The butter is used in _Homa_ (the offering). The Homa is the cause of the clouds. The clouds give rain. The rain makes the seeds to sprout forth and produce food.” The Voice said: “Who is spoken of as the unconquered enemy of man? What is spoken of as the enemy's disease? Who is regarded as holy? Who is regarded as unholy?” Said Yudhishthira: “Man's unconquered enemy is anger, and his disease is covetousness; he who seeketh after the good of all is holy; he who is selfishly cold is unholy.” The Voice said: “Who are worthy of eternal torment?” Said Yudhishthira: “He who sayeth unto the Brahman whom he hath asked to his house, I have naught to give; he who declareth the Vedas to be false; he who is rich and yet giveth naught to the poor.” Many such questions did the Voice address to wise Yudhishthira, and he answered each one patiently and with knowledge. Then the Yaksha revealed himself in the form of Dharma, god of wisdom and justice, for behold! he was the celestial sire of Yudhishthira. Unto his son he granted two boons; and Yudhishthira desired that his brethren should be restored to life, and that they should all have power to remain unrecognized by anyone in the three worlds for the space of a year. Ere the Pandavas left the forest, Yudhishthira invoked the goddess Durga[276], giver of boons, saying: “O slayer of the Buffalo Asura, thou art worshipped by the gods, for thou art the protector of the three worlds. Chief of all deities, protect thou and bless thou us. Confer victory upon us, and help us in our distress.” [276] A form of the goddess Kali, wife of Shiva. The goddess heard Yudhishthira, and confirmed the promise of Dharma that the Pandava brethren and Draupadi would remain unrecognized during the thirteenth and last year of their exile. Then the wanderers concealed their weapons in a tree, and went together towards the city of Virata[277] so that they might conceal themselves. According to the terms of banishment, they would have to spend a further twelve years in the jungle if the Kauravas discovered their whereabouts. [277] _Pron._ vir-at´a.
