Brahman is the name the Upaniṣads give to the absolute: being, consciousness and bliss, beyond every description, yet present as the self of all. The word first meant the power of sacred speech in the Vedic ritual and came to mean the ground of everything. The schools of Vedānta differ on whether Brahman is without attributes or is the personal Lord with infinite good qualities.
Brahman
In the Upaniṣads and Vedānta, the ultimate reality from which all things arise, by which they live and into which they return.
