It is the deep urge to be one with the whole, the deep urge to dissolve I and thou into one unity. Love is that because we are separated from our own source, out of that separation the desire arises to fall back into the whole, to become one with it.
Each moment life is new and you have to respond from your inner newness, you have to be available to the new as the new. And you have to respond, not out of your knowledge, but out of your present awareness. Only then life works, otherwise life stops working. If your life is not working, remember, it is the ego that is hindering, the mechanical has encroached upon the organic. To be free from the mechanical is to be in God, because it is to be in the organic unity of existence.
