“There has to be a moment at the beginning when you wonder whether you’re in love with the person or in love with the feeling of love itself.”

Context: We know only fragmentarily this extraordinary thing called life; we have never looked at sorrow, except through the screen of escapes; we have never seen the beauty, the immensity of death, and we know it only through fear and sadness. There can be understanding of life, and of the significance and beauty of death, only when the mind on the instant perceives “what is”. You know, sirs, although we differentiate them, love, death, and sorrow are all the same; because, surely, love, death, and sorrow are the unknowable. The moment you know love, you have ceased to love. Love is beyond time; it has no beginning and no end, whereas knowledge has; and when you say, “I know what love is”, you don’t. You know only a sensation, a stimulus. You know the reaction to love, but that reaction is not love. In the same way, you don’t know what death is. You know only the reactions to death, and you will discover the full depth and significance of death only when the reactions have ceased.

Context: Love is always new. Regardless of whether we love once, twice, or a dozen times in our life, we always face a brand-new situation. Love can consign us to hell or to paradise, but it always takes us somewhere. We simply have to accept it, because it is what nourishes our existence. If we reject it, we die of hunger, because we lack the courage to reach out a hand and pluck the fruit from the branches of the tree of life. We have to take love where we find it, even if it means hours, days, weeks of disappointment and sadness.
The moment we begin to seek love, love begins to seek us.
And to save us.

Separation has this lofty meaning...
