When you were in love, you were capable of learning everything and of knowing things you had never dared even to think, because love was the key to understanding all of the mysteries.
The Buddha is your real body, your original mind. This mind has no form or characteristics, no cause or effect, no tendons or bones. It's like space. You can't hold it. It's not the mind of materialists or nihilists. If you don't see your own miraculously aware nature, you'll never find a Buddha, even if you break your body into atoms.
If you have no love, do what you will - go after all the gods on earth, do all the social activities, try to reform the poor, the politics, write books, write poems - you are a dead human being. Without love your problems will increase, multiply endlessly.
