Mahat-tattva
Mahat-tattva (Sanskrit: महत्तत्त्व, romanized: Mahattattva) or mahat is a concept in the Samkhya philosophy of Hinduism. It is the first evolute of Prakriti, the causeless cause of the world, that is generated after Prakriti begins to evolve when its equilibrium is disturbed, which causes expansion of material energy and matter.
