“ The secret of enlightenment is the absolute, unequivocal conviction that it exists.What does that mean? It means you have discovered an unshakable confidence in the fact of nonduality—in the perennial mystical revelation that IT IS . . . and I AM THAT. A confidence in that which can never be seen or known is the very ground of the enlightened state. Being is ungraspable, it’s unknowable, it’s ever elusive, and yet it is the only place you can find true confidence in life. Why? Because it is the very source of life itself.The conscious experience of Being, which is what enlightenment is, has always been the ultimate answer to the most fundamental spiritual questions: Who am I? and Why am I here? Those who have tasted enlightened awareness find that in that experience, any trace of existential doubt and all the questions that go along with it instantaneously disappear. It’s not even that they are answered, but rather, the questions lose their meaning. When you locate the nonrelative, or absolute, nature of consciousness in the depths of your own self, it is experienced as a clarity that is empty of content; a weightiness that is full of nothing in particular; a profound knowing that dissolves all questions. In that questionless state, you find yourself profoundly rooted and radically free, supported by an absolute confidence in the knowing of no-thing that changes everything. The experience of that empty ground is the answer—the one answer that always liberates each and every one of us. You simply know, unequivocally, before thought, that I am. That’s the only answer: I AM. There is no why. ”
