Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Of the Vedas I am the Sama Veda; of the demigods I am Indra, the king of heaven; of the senses I am the mind; and in living beings I am the living force [consciousness].

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The difference between matter and spirit is that matter has no consciousness like the living entity; therefore this consciousness is supreme and eternal. Consciousness cannot be produced by a combination of matter.
