Love is the only real intoxicant. And it has a very paradoxical quality to it:

it intoxicates you and yet it makes you more aware. That’s the miracle of love. It does not make you unconscious. If it makes you unconscious it is lust, not love.

If it makes you drunk and yet in the deepest core of your being you become more and more alert and conscious, then it is love.

One can be aware without love, but then awareness is almost like a wasteland, a desert. Nothing grows, no flowers, no trees. Love can be without awareness but then it is simply sexuality, animal lust, nothing higher than that - something biological, physical, chemical. But when both are together, love and awareness, they create a great harmony.
