In the beginning of the Kalpa, as Brahmá purposed to create a son, who should be like himself, a youth of a purple complexion appeared, crying with a low cry, and running about. Brahmá, when he beheld him thus afflicted, said to him, "Why dost thou weep?" "Give me a name," replied the boy. "Rudra be thy name," rejoined the great father of all creatures: "be composed; desist from tears." But, thus addressed, the boy still wept seven times, and Brahmá therefore gave to him seven other denominations; and to these eight persons regions and wives and posterity belong. The eight manifestations, then, are named Rudra, Bhava, Śarva, Iśána, Paśupati, Bhíma, Ugra, and Mahádeva, which were given to them by their great progenitor. He also assigned to them their respective stations, the sun, water, earth, air, fire, ether, the ministrant Brahman, and the moon; for these are their several forms. The wives of the sun and the other manifestations, termed Rudra and the rest, were respectively, Suverchalá, Ushá, Vikesí, Sivá, Swáhá, Diśá, Díkshá, and Rohiní. Now hear an account of their progeny, by whose successive generations this world has been peopled. Their sons, then, were severally, Sanaiśchara (Saturn), Śukra (Venus), the fiery-bodied Mars, Manojava (Hanumán), Skanda, Swarga, Santána, and Budha (Mercury).
