Mbh 14.3.1a

"'Vyasa said, "O Yudhishthira, thy wisdom, I conceive, is not adequate. None doth any act by virtue of his own power. It is God, who engageth him in acts good or bad, O bestower of honour. Where then is the room for repentance? Thou deemest thyself as having perpetrated impious acts. Do thou, therefore, O Bharata, harken as to the way in which sin may be removed. O Yudhishthira, those that commit sins, can always free themselves from them through penance, sacrifice and gifts. O king, O foremost of men, sinful people are purified by sacrifice, austerities and charity. The high-souled celestials and Asuras perform sacrifices for securing religious merit; and therefore sacrifice are of supreme importance. It is through sacrifices that the high-souled celestials had waxed so wondrously powerful; and having celebrated rites did they vanquish the Danavas. Do thou, O Yudhishthira, prepare for the Rajasuya, and the horse-sacrifice, as well as, O Bharata, for the Sarvamedha and the Naramedha.[2] And then as Dasaratha's son, Rama, or as Dushmanta's and Sakuntala's son, thy ancestor, the lord of the Earth, the exceedingly puissant king Bharata, had done, do thou agreeably to the ordinance celebrate the Horse-sacrifice with Dakshinas." Yudhishthira replied, "Beyond a doubt, the Horse-sacrifice purifieth princes. But I have a purpose of which it behoveth thee to hear. Having caused this huge carnage of kindred, I cannot, O best of the regenerate ones, dispense gifts even on a small scale; I have no wealth to give. Nor can I for wealth solicit these juvenile sons of kings, staying in sorry plight, with their wounds yet green, and undergoing suffering. How, O foremost of twice-born ones, having myself destroyed the Earth can I, overcome by sorrow, levy dues for celebrating a sacrifice? Through Duryodhana's fault, O best of ascetics, the kings of the Earth have met with destruction, and we have reaped ignominy.
