guṇah
Attribute; quality; particular modification; adjective; sattvaṃ rajas tamas as constituents of māyā; knot; the vowels a, e, o.
In Vedanta
The three constituents of māyā — sattva (knowledge, clarity), rajas (activity, restlessness), and tamas (inertia, concealment). All material manifestation is a combination of these three. The guṇas belong to prakṛti/māyā, not to ātmā. Ātmā is nirguṇa — free from all guṇas. Understanding this distinction is essential to recognizing oneself as actionless, unchanging awareness.
