Mahabharata Shalya Parva Chapter 43

Mahabharata Shalya Parva (Gada Yuddha Parva) Chapter 43 Vaishampayana said, "Cursed by the intelligent Vishvamitra in anger, Sarasvati, in that auspicious and best of tirthas, flowed, bearing blood in her current. Then, O king, many Rakshasas came, O Bharata, and lived happily there, drinking the blood that flowed. Exceedingly gratified with that blood, cheerfully and without anxiety of any kind, they danced and laughed there like persons that have (by merit) attained to heaven. After some time had passed away, some Rishis, possessed of wealth of asceticism, came to the Sarasvati, O king, on a sojourn to her tirthas. Those foremost of Munis, having bathed in all the tirthas and obtained great happiness, became desirous of acquiring more merit. Those learned persons at last came, O king, to that tirtha where the Sarasvati ran a bloody current. Those highly blessed ones, arriving at that frightful tirtha, saw the water of the Sarasvati mixed with blood and that innumerable Rakshasas, O monarch, were drinking it. Beholding those Rakshasas, O king, those ascetics of rigid vows made great endeavours for rescuing the Sarasvati from that plight. Those blessed ones of high vows, arrived there, invoked that foremost of rivers and said these words unto her, 'Tell us the reason, O auspicious lady, why this lake in thee hath been afflicted with such distress. Hearing it, we shall endeavour (to restore it to its proper condition).' Thus questioned, Sarasvati, trembling as she spoke, informed them of everything that had occurred. Seeing her afflicted with woe, those ascetics said, 'We have heard the reason. We have heard of thy curse, O sinless lady! All of us shall exert ourselves!' Having said these words unto that foremost of rivers, they then consulted with one another thus, 'All of us shall emancipate Sarasvati from her curse.' Then all those Brahmanas, O king, worshipping Mahadeva, that lord of the universe and protector of all creatures, with penance and vows and fasts and diverse kinds of abstinences and painful observances, emancipated that foremost of rivers, the divine Sarasvati. Beholding the water of Sarasvati purified by those Munis, the Rakshasas (that had taken up their abode there), afflicted with hunger, sought the protection of those Munis themselves. Afflicted with hunger, the Rakshasas, with joined hands, repeatedly said unto those ascetics filled with compassion, these words, 'All of us are hungry! We have swerved from eternal virtue! That we are sinful in behaviour is not of our free will! Through the absence of your grace and through our own evil acts, as also through the sexual sins of our women, our demerits increase and we have become Brahma-Rakshasas! So amongst Vaisyas and Sudras, and Kshatriyas, those that hate and injure Brahmanas became Rakshasas. Ye best of Brahmanas, make arrangements then for our relief! Ye are competent to relieve all the worlds!' Hearing these words of theirs, those ascetics praised the great river. For the rescue of those Rakshasas, with rapt minds those ascetics said, 'The food over which one sneezed, that in which there are worms and insects, that which may be mixed with any leavings of dishes, that which is mixed with hair, that which is mixed with tears, that which is trodden upon shall form the portion of these Rakshasas! The learned man, knowing all this, shall carefully avoid these kinds of food. He that shall take such food shall be regarded as eating the food of Rakshasas!' Having purified the tirtha in this way, those ascetics thus solicited that river for the relief of those Rakshasas.
