What is thathuvam means?

Thathuvam means "principle" or "axiom" in Tamil. It is a fundamental truth or proposition that serves as the basis for a system of thought or belief. Thathuvam is often used in the context of philosophy, religion, and science to refer to the underlying principles that govern the world and our understanding of it. For example, in the philosophy of Advaita Vedanta, the thathuvam is the principle of non-duality, which states that the individual soul (atman) and the universal soul (Brahman) are one and the same. In science, the thathuvam of the conservation of energy states that energy can neither be created nor destroyed, only transferred or transformed.
