Aditi (the light), in Hindu mythology, is one of the two wives of Kasyapa; the other, Diti, is the darkness. Aditi is a personification of the day, and therefore is. the daughter of Daksha and the mother, of the twelve Adityas. Aditi and Kasyapa sprang from Brahma, and are therefore called children of God. Because of their great light, they are called the source. of light.
Aditi and Kasyapa are the parents of Indra, the first of the twelve Adityas. The latter were pressed hard by the sons of the giants in a frightful war. Aditi asked her husband what she should do. He advised her to bringaan offering to the honor of Vishnu, who would be born as her Son, and would annihilate the giants: It happened so; and thus Aditi gave birth to Vishnu in the person of the dwarf Vamana.
