Context: The truths of the ṛṣis are not evolved as the result of logical reasoning or systematic philosophy but are the products of spiritual intuition, dṛṣti or vision. The ṛṣis are not so much the authors of the truths recorded in the Vedas as the seers who were able to discern the eternal truths by raising their life-spirit to the plane of universal spirit. They are the pioneer researchers in the realm of the spirit who saw more in the world than their followers. Their utterances are not based on transitory vision but on a continuous experience of resident life and power. When the Vedas are regarded as the highest authority, all that is meant is that the most exacting of all authorities is the authority of facts.
