Series 2, Chapter 13 pg 414, Para 2: All these things taken together constitute the fundamental character of our first transactions with the world of Nature, but it is evidently not the whole description of our being; it is our actuality but not the limit of our possibilities. There is something beyond to be known, jneyam, and it is when the knower of the field turns from the field itself to learn of himself within it and of all that is behind its appearances that real knowledge begins, jnanam, — the true knowledge of the field no less than of the knower. That turning inward alone delivers from ignorance. For the farther we go inward, the more we seize on greater and fuller realities of things and grasp the complete truth both of God and the soul and of the world and its movements. Therefore, says the divine Teacher, it is the knowledge at once of the field and its knower, ksetra-ksetrajnayor jnanam, a united and even unified self-knowledge and world-knowledge, which is the real illumination and the only wisdom. For both soul and nature are the Brahman, but the true truth of the world of Nature can only be discovered by the liberated sage who possesses also the truth of the spirit. One Brahman, one reality in Self and Nature is the object of all knowledge.
