jñāna / ज्ञान: / knowledge, as the nature of Brahman
Jñāna in the context of Brahman is the knowledge which characterizes its very essence. Brahman itself is uncontracted, infinite knowledge.
Ramanuja emphasizes that this is not merely abstract knowledge, but is the active, self-luminous, and all-pervading nature of Brahman, capable of illuminating all.
