(In brief and essential terms)
अ॒ग्निर्हि दे॒वाँ अ॒मृतो॑ दुव॒स्यत्यथा॒ धर्मा॑णि स॒नता॒ न दू॑दुषत्॥1
The immortal mystic fire of aspiration adores cosmic powers and beings so that the eternal principles of Dharma may not be violated.
The concepts of Dharma and Karma have been derived from some of the important discoveries which were made by the Vedic Rishis. We shall refer mainly to five of these discoveries.
Modern knowledge acknowledges the existence of Matter, which we can sense through our sense-organs; it also accepts the existence of Life that pulsates in the universe through the process of association, growth and disintegration; it further admits Mind as the power and substance of Idea or Thought. But it has still not rediscovered the Vedic “fourth world” that is superior to idea and which can be described as Real-Idea, since it is regarded as capable of realising ideative concepts.
