You know when you're in love, when you can't fall asleep, because reality is finally better than your dreams.
Love is possible only if two persons communicate with each other from the center of their existence, hence if each one of them experiences himself from the center of his existence. Only in this central experience is human reality, only here is aliveness, only here is the basis for love. Love, experienced thus is a constant challenge, it is not a resting place, but a moving, growing, working together, they are one with each other by being one with themselves.
Love is being honest with yourself at all times. Being honest with the other person at all times. Telling, listening, respecting the truth and never pretending. Love is the source of reality.
