Hindu philosophy encompasses a diverse range of ideas and beliefs that originate from the ancient texts of Vedas and Upanishads. It explores fundamental questions about existence, the nature of reality, and the self. Key concepts include dharma (duty), karma (action and its consequences), and moksha (liberation from the cycle of birth and death). There are six main schools of Hindu philosophy, known as darshanas, which include Nyaya, Vaisheshika, Sankhya, Yoga, Mimamsa, and Vedanta. Each school offers unique perspectives on knowledge, ethics, and the ultimate purpose of life, contributing to the rich tapestry of Hindu thought.
