I will declare the one object to which the mind of spiritual knowledge must be turned, by fixity in which the soul clouded here recovers and enjoys its nature and original consciousness of immortality, – the eternal supreme Brahman called neither Sat (existence) nor Asat (non-existence).
Gītā 13·13To enjoy the eternity to which birth and life are only outward circumstances, is the soul’s true immortality and transcendence. That Eternal or that Eternity is the Brahman. Brahman is That which is transcendent and That which is universal: it is the free spirit who supports in front the play of soul with nature and assures behind their imperishable oneness; it is at once the mutable and the immutable, the All that is the One. In his highest supracosmic status Brahman is a transcendent Eternity without origin or change far above the phenomenal oppositions of existence and non-existence, persistence and transience between which the outward world moves.
