The best use of imagination is creativity. The worst use of imagination is anxiety.
As human beings we have unlimited potential and imagination. The worst thing you can do is be a conformist and buy into conformity. It's the worst possible thing. It's better to be outrageous. It's better to hang out with the sages, the people open to possibilities, even the psychotics. You never know where you'll find the geniuses of our society.
We're living in a time when the world has suddenly discovered India because it's run out of raw material for its imagination. The raw materials for imagination are inexhaustible here.
We're not in the physical world. The physical world is in us. We create the physical world when we perceive it, when we observe it. And also we create this experience in our imagination. And when I say "we," I don't mean the physical body or the brain, but a deeper domain of consciousness which conceives, governs, constructs and actually becomes everything that we call physical reality.
In the deepest realm of being, is the imagination of ourselves. What is your next evolutionary leap? What are you imagining, (for yourself) right now?
Your body, which is very physical, is under the influence of your thoughts, your feelings, your emotions, your dreams, your fantasies, your desires, your instincts, your drives, your imagination. All these things orchestrate themselves - all these internal activities that are in the invisible domain that we call consciousness actually have very precise physical effects both in our biology, but they also influence our perception of the world.
