One of the most prominent of these Rishis is Na´rada[187], who cursed and was cursed by Brahma. In the _Mahábhárata_ he is a renowned teacher and a counsellor of kings, and also a messenger between Indra and heroes. He is a patron of music, and invented the Vina (lute) on which he loves to play. His great rival is Parvata, who also acts as a Celestial messenger. [187] Or Nãrada. Daksha is the father of Sati, the peerless wife of Shiva. It was on account of this rishi's quarrel with her husband, who was not invited to a great feast, that she flung herself upon the sacrificial fire. Shiva cut off Daksha's head and replaced it with the head of a goat. Bhrigu was the patriarch of a Vedic priestly family. He married a daughter of Daksha, and was the father of Lakshmi, wife of Vishnu, who rose from the ocean of milk. Bhrigu once cursed Agni, whom he compelled to consume everything. Angiras, Kratu, and Pulaha were Deva-rishis who also married daughters of Daksha. Pulastya was a famous slayer of Rakshasas. He once cursed a king who refused to make way for him on a narrow forest path, and the king became a Rakshasa. Marichi was the grandfather of the dwarf incarnation of Vishnu, and Atri was the father of the irascible sage Durvasas, a master curser. Vasishtha is sometimes referred to as identical with Vyasa, the reputed arranger of the Vedas, and author of the _Mahábhárata_. He possessed a wonderful cow which granted whatever he wished for. A king named Vishwamitra desired to possess this wonderful animal, and when he found that he was unable to obtain it by force, he determined to raise himself from the Kshatriya to the Brahman caste by performing prolonged austerities. When Vishwamitra secured this elevation he fought with his rival. Some Vedic scholars regard Vishwamitra and Vasishtha as actual historical personages. They argue that Vishwamitra was originally a Purohita (family priest) in the service of Sudas, the king of an Aryan tribe called the Tritsus. References are found in the _Rigveda_ to the wars of Sudas, who once defeated a coalition of ten kings. Vishwamitra is believed to have been deposed by Sudas in favour of Vasishtha, and to have allied himself afterwards with the enemies of the Tritsus.[188] [188] _Rigveda_, viii, 53. 9-11, and vii, 18. Professor Oldenberg, the German Sanskrit scholar, is convinced, however, that there is no evidence in the _Rigveda_ of the legendary rivalry between Vishwamitra and Vasishtha. He regards the Vasishthas as the family priests of the Bharata tribe and identical with the Tritsus. [Illustration: PARVATI, WIFE OF SHIVA (see page 150) _From a South Indian temple_ 30]
