A muni in the highest tradition, "United with the One" by withdrawal of the mind at will from objects of the senses and from attraction to them, Kapila is also the inspired author of the Sanhkya philosophy.

Swami Vivekananda -

The greatest psychologist the world has ever known, Bhagavan Kapila, demonstrated ages ago that human consciousness is one of the elements in the make-up of all the objects of our perception and conception, internal as well as external.

The father of our psychology, Kapila, denies the existence of God. His idea is that a Personal God is quite unnecessary; nature itself is sufficient to work out the whole of creation. What is called the Design Theory, he knocked on the head, and said that a more childish theory was never advanced. But he admits a peculiar kind of God. He says we are all struggling to get free; and when we become free, we can, as it were, melt away into nature, only to come out at the beginning of the next cycle and be its ruler. We come out omniscient and omnipotent beings. In that sense we can be called Gods; you and I and the humblest beings can be Gods in different cycles. He says such a God will be temporal; but an eternal God, eternally omnipotent and ruler of the universe cannot be. If there was such a God, there would be this difficulty: He must be either a bound spirit or a free one. A God who is perfectly free would not create: there is no necessity for it. If He were bound, He would not create, because He could not: He would be powerless. In either case, there cannot be any omniscient or omnipotent eternal ruler. In our scriptures, wherever the word God is mentioned, he says, it means those human beings who have become free.
