The cosmic order is controlled by a fundamental moral principle. An eternal law or unity, which can be conceived as the principle of rightness or justice, regulates all phenomena. In the Veda, this is called "Rtam", which means the fixed way or course, in other words, the settled order of things. The whole universe is founded on Rtam and moves in it. It keeps all things and beings in their respective courses. Consequently nothing deviates from its own nature. Because of Rtam, fire burns, wind blows, water flows, plants grow and the seasons revolve. Rtam maintains regularity in the movements of the Sun and Moon, the planets and other luminaries. It manifests itself as the universal law of causation which finds expression in the human plane as the law of Karma. It establishes unity between the Cosmic forces and the individual powers. It is the basis of all laws, physical, biological, psychical, moral and spiritual. Rtam regulates Dharma, the principle of equity, the moral law that governs human life. because of this, right deed inevitably produces good result whereas wrong deed leads to evil consequences. There is no unmerited happiness or misery, gain or loss in mans life."
