Mbh 13.150.2e

One should, indeed, take the name of that dear son of Vudha. One should also take the name of Bharata, that hero celebrated over the three worlds. He also who in the Krita age adored the gods in a grand Gomedha sacrifice, viz., Rantideva of great splendour, who was equal unto Mahadeva himself, should be named. Endued with penances, possessed of every auspicious mark, the source of every kind of benefit to the world, he was the conqueror of the universes. One should also take the name of the royal sage Sweta of illustrious fame. He had gratified the great Mahadeva and it was for his sake that Andhaka was slain. One should also take the name of the royal sage Bhagiratha of great fame, who, through the grace of Mahadeva, succeeded in bringing down the sacred river from heaven (for flowing over the earth and cleansing all human beings of their sins). It was Bhagiratha who caused the ashes of the sixty thousand sons of Sagara to be overflowed with the sacred waters of Ganga and thereby rescued them from their sin. Indeed, one should take the names of all these that were endued with the blazing effulgence of fire, great beauty of person, and high energy. Some of them were of awe-inspiring forms and great might. Verily, one should take the names of these deities and Rishis and kings, those lords of the universe,--who are enhancers of fame. Sankhya, and Yoga which is highest of the high, and Havya and Kavya and that refuge of all the Srutis, viz., Supreme Brahma, have been declared to be the sources of great benefit to all creatures. These are sacred and sin-cleansing and have been spoken of very highly. These are the foremost of medicines for allaying all diseases, and are the inducers of the success in respect of all deeds. Restraining one's senses, one should, O Bharata, take the names of these, morning and evening. It is these that protect. It is these that shower rain. It is these that shine and give light and heat. It is these that blow.
