Surrender is the decision taken to hand over the responsibility of your life to the Divine. Without this decision nothing is at all possible; if you do not surrender, the Yoga is entirely out of the question. Everything else comes naturally after it, for the whole process starts with surrender. You can surrender either through knowledge or through devotion.
You may have a strong intuition that the Divine alone is the truth and a luminous conviction that without the Divine you cannot manage. Or you may have a spontaneous feeling that this line is the only way of being happy, a strong psychic desire to belong exclusively to the Divine: “I do not belong to myself,” you say, and give up the responsibility of your being to the Truth.
Then comes self-offering: “Here I am, a creature of various qualities, good and bad, dark and enlightened. I offer myself as I am to you, take me up with all my ups and downs, conflicting impulses and tendencies—do whatever you like with me.”
In the course of your self-offering, you start unifying your being around what has taken the first decision—the central psychic will. In the beginning you start by making this offering in a general way, as though once for all; you say, “I am the servant of the Divine; my life is given absolutely to the Divine; all my efforts are for the realisation of the Divine Life.” But that is only the first step; for this is not sufficient.
When the resolution has been taken, when you have decided that the whole of your life shall be given to the Divine, you have still at every moment to remember it and carry it out in all the details of your existence. This is what you have to do to carry out your general offering in detailed offerings. Live constantly in the presence of the Divine; live in the feeling that it is this presence which moves you and is doing everything you do.
Offer all your movements to it, not only every mental action, every thought and feeling but even the most ordinary and external actions such as eating; when you eat, you must feel that it is the Divine who is eating through you. When you can thus gather all your movements into the One Life, then you have in you unity instead of division.
