Whether you are guided by your emotions or guided by your intellect, it leads to despair because it leads nowhere. But you realize that love is not pleasure, love is not desire.
You know what pleasure is, sir? When you look at something or when you have a feeling, to think about that feeling, to dwell constantly upon that feeling gives you pleasure, and that pleasure you want and you repeat that pleasure over and over again. When a man is very ambitious or a little ambitious, that gives him pleasure. When a man is seeking power, position, prestige in the name of the country, in the name of an idea, and all the rest of it, that gives him pleasure. He has no love at all, and therefore he creates mischief in the world. He brings about war within and without.
So one has to realize that emotions, sentiment, enthusiasm, the feeling of being good, and all that have nothing whatsoever to do with real affection, compassion. All sentiment, emotions have to do with thought and therefore lead to pleasure and pain. Love has no pain, no sorrow, because it is not the outcome of pleasure or desire.
