One of the Prajapatis, or lords of creation.
Daksha had many daughters, of whom twenty-seven were lunar goddesses married to Soma, god of the moon, Daksha thought that Soma was favouring one of his daughters, Rohini, more than her sisters. To punish Soma he infected him with consumption. His other daughters objected strongly to losing their husband so Daksha made the illness periodic and not permanent. This accounts for the weakening of the moon's powers every month.
Another of Daksha's daughters, the beautiful Sati, fell in love with the god Siva. Daksha was annoyed for he didn't like Siva. He arranged a betrothal ceremony during which his daughter would choose a husband from among the assembled suitors. He was careful not to invite Siva. At the ceremony, Sati looked about her and realized what her father had done. She took the garland which was to be placed about the chosen bridegroom's neck, and tossed it into the air. Miraculously Siva materialized, with the garland about his neck; the sign that he had been chosen by Sati. Daksha was outmanoeuvred for the time being, but he loathed Siva for his part in rituals of destruction and later found an excuse to go to war against him.
