(Ākāśa): Radiance. This term refers to Ether, the most subtle of the five tattvas (fundamental elements) that create the physical Cosmos. Derived from the Sanskrit root kas, meaning “to be visible” or “to shine,” akasha shines in all directions. Akasha also signifies Infinite Space, the sky, and infinity. Beyond its physical designations, akasha is another name for Brahman (the Supreme Reality).
