(Indra on his mount Airavata)

Lord of the devas (celestials). (Glossary for the Vahinis)

Indra is one who has the form of Virata and gives all the Aishvarya or wealth.Surya, the sun will have the form of Hiranyagarbha. Vasu stands for one who eradicates the sorrow. In this context, we know that Indra is present in waking state, that Hiranyagarbha is present in the dream state and that Vasu is present in the deep sleep state. While they correspond to these three respective states, they are not functioning independently in these states. While these three are not fully independent, they do not act on their own these states. Brahman remains fully independent and remains as the basis and makes them function according to His own wish. (SSB 1974, pp. 206-207)
