Series 1, Chapter 10 pg 101, Para 2: This cannot be done perfectly by the act of the intelligence itself, by a merely mental self-discipline; it can only be done by Yoga with something which is higher than itself and in which calm and self-mastery are inherent. And this Yoga can only arrive at its success by devoting, by consecrating, by giving up the whole self to the Divine, “to Me”, says Krishna; for the Liberator is within us, but it is not our mind, nor our intelligence, nor our personal will, — they are only instruments. It is the Lord in whom, as we are told in the end, we have utterly to take refuge. And for that we must at first make him the object of our whole being and keep in soul-contact with him. This is the sense of the phrase “he must sit firm in Yoga, wholly given up to Me”; but as yet it is the merest passing hint after the manner of the Gita, three words only which contain in seed the whole gist of the highest secret yet to be developed. Yukta asita matparah.
