The Attribute That Knows
Dharma-bhūta-jñāna ('knowledge that is an attribute/dharma') is one of the most distinctive concepts of Vishishtadvaita epistemology and psychology. It distinguishes between the jīva's essential self (svarūpa) and its cognitive attribute (dharma-bhūta-jñāna). The ātman's svarūpa is aṇu (atomic), but its dharma-bhūta-jñāna is a separate category that can expand like light to illuminate objects far from the self.
Why This Distinction Matters
This distinction solves a problem: if the jīva's essential self is aṇu (atomic/point-like), how can it know vast objects? Vishishtadvaita answers: the ātman's knowing is done not directly by the svarūpa but by this attribute-consciousness (dharma-bhūta-jñāna) which, like a lamp's light, reaches outward from the tiny lamp to illuminate a large room.
Expansion and Contraction
In the bound state (saṃsāra), karma and māyā contract the dharma-bhūta-jñāna — the bound soul's knowledge is limited, distorted, and colored by its attachments and ignorance. This contraction is the cause of all epistemic errors (viparyaya). In liberation (mokṣa), dharma-bhūta-jñāna expands fully and without obstruction — the liberated soul can know Brahman and all of Brahman's perfections directly and continuously.
Distinction from Brahman's Knowledge
Brahman's jñāna is intrinsic to His svarūpa — His knowing and His being are identical. The jīva's knowing is always a separate attribute (dharma) that belongs to its svarūpa but is distinct from it. This preserves the ontological difference between Brahman and jīva even in liberation.
