Lokayata is an ancient Indian philosophical system that emphasizes a materialistic and empirical approach to understanding the world. It rejects supernatural explanations and focuses on direct experience and observation as the basis for knowledge. The philosophy advocates for a life grounded in the physical world, often critiquing religious and metaphysical beliefs. The term "Lokayata" can also refer to the broader tradition of Carvaka, which is known for its skepticism towards spiritual doctrines. Proponents of Lokayata argue that pleasure and well-being in this life are paramount, promoting a hedonistic view that values sensory experiences over abstract ideals.
