‘Brahmaṇaspati’ is one of the names that occurs in the Ṛgveda as also in the Śatapatha Brāhmaṇa. He may be the deity of prayer and of the text of the Veda itself. He is said to control the clouds and rain and help the world by protecting vegetation.
Scholars differ as regards his exact identity. He is identified with several roles: Agni (the fire-god), the priest of god Indra, deity of vegetation and hence a form of candra or the moon and so on.
There is reason to believe that Brahmaṇaspati is another name for Bṛhaspati, the preceptor of the gods.
