“Creative insight is not the final link in a chain of reasoning. If it were that, it would not strike us as inspired in its origin. Intuition is not the end, but part of an ever-developing and ever-dynamic process of realization. There is continual system of “checks and balances” between intuition and the logical method of discursive reasoning. Cognitive intuitions are not substitutes for thought, they are challenges to intelligence. Mere intuitions are blind while intellectual work is empty. All processes are partly intuitive and partly intellectual. There is no gulf between the two.”

Context: Reason alone will not serve. Intuition alone can be improved by reason, but reason alone without intuition can easily lead the wrong way. They both are necessary. The way I like to put it is that when I have an intuition about something, I send it over to the reason department. Then after I've checked it out in the reason department, I send it back to the intuition department to make sure that it's still all right. That's how my mind works, and that's how I work. That's why I think that there is both an art and a science to what we do. The art of science is as important as so-called technical science. You need both. It's this combination that must be recognized and acknowledged and valued.

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.
