Ilā The Rgveda (1.13.9) mentions Ilā along with Sarasvatī and Mahī—as a goddess of light and brilliance. She is the goddess of the earth. In another place (1.31.11) she is declared as the daughter of Manu and the teacher of men. Her place is the centre of the earth. On the sacrificial altar, the place sanctified by her feet, is used for keeping the fire of the sacrifice. In the purāṇas and the Mahābhārata, she is pictured as the daughter of Manu. Due to several reasons like entering a forbidden place or the efforts of the sages like Vasiṣṭha she undergoes change of sex, becoming the prince Sudyumna or the wife of Budha (and mother of Pururavas) and so on. She used to undergo change of sex once a month! See also IDĀ.
