Although encouraged by the demigods to maintain the child, Mamatā considered him useless because of his illicit birth, and therefore she left him. Consequently, the demigods known as the Maruts maintained the child, and when Mahārāja Bharata was disappointed for want of a child, this child was given to him as his son.

From this verse it is understood that those who are rejected from the higher planetary system are given a chance to take birth in the most exalted families on this planet earth.
