Brahman is a Sanskrit term meaning both the Consciousness of Brahman (see the article
Holy Spirit) and a person who cognized Brahman (see the articles
In order to clarify the meaning of the word Brahman, it needs to say a few words about the ancient Indian philosophical system of knowledge called Vedanta.
The Vedanta philosophy originated in India even before Krishna and was based on the pagan teachings of the four Vedas. At that time, Indian people did not know about the existence of Ishvara — God-the-Father (i.e. the Creator Who dwells in His Abode). This was the reason why Brahman was considered by the Vedanta philosophy as the Supreme Godhead and even as the Absolute.
It was Krishna Who told people of India about God-the-Father.
In the Bhagavad Gita He also outlines the difference between the concepts of Ishvara and Brahman:
“14:27. … Brahman, imperishable and immortal, is based on Me. I am the Basis of eternal dharma and the Abode of the ultimate happiness.”
“3:15. Know that realization of destinies originates from Brahman. And Brahman represents the Supreme. Omnipresent Brahman always supports sacrifice.”
“14:3. For Me the womb is Great Brahman. Into Him I introduce the semen and this results in birth of all beings, O Bharata.
“14:4. In whatever wombs mortals are born, O Kaunteya, Brahman is their Supreme Womb. And I am the Father Who procreates them.”
