Whatever truly exists is the Real. Logically, attribute or quality itself becomes an unsound concept when it is extended to the Absolute. A thing has an attribute only in relation to another thing. There is no meaning in saying that a substance has an attribute when that substance alone is said to exist. The nature of a self-existent absolute principle is indeterminable.
Every attribute limits it and creates a difference in non-difference.
Brahman cannot be said to have any intelligible attribute, for Brahman is the entire existence and has nothing second to relate itself to. Every qualitative concept involves relations, and every thought creates a duality. To think Brahman is to reduce Brahman to the world of experience. Thought is possible only in an individualised state, but Brahman is not an individual, and is unapproachable by an individual. Brahman cannot even be conceived of as light, for it has nothing to shine upon.
