Of the Vedas I am the Sama Veda; of the devas I am Vasava (Indra); of the senses I am the mind; and in all living beings I am the consciousness. (Bhagavad Gita Chapter X – Verse 22)
Of the four Vedas I am the Sama Veda. The Vedas are divided into four parts: the Rig Veda, the Yajur Veda, the Atharva Veda and the Sama Veda. Of these four, I am the Sama Veda, which contains beautiful hymns and chants. Among the gods, I am Indra, their king. I am the mind; I am the consciousness.
Of the Rudras I am Shankara; of the Yakshas and Rakshasas I am the Lord of Wealth; of the Vasus I am the Fire-god; among the mountains I am Meru. (Bhagavad Gita Chapter X – Verse 23)
OPartha, know Me to be Brihaspati, the chief priest; of generals I am Skanda; among waters I am the ocean. (Bhagavad Gita Chapter X – Verse 24)
The Rudras are the twelve gods of knowledge. Yakshas are sensual spirits. Rakshasas are evil spirits. Meru is the celestial mountain where the gods dwell. Skanda is the leader of the celestial hosts.
