Thomas Cathcart said this quote

It's only when we dare to experience the full anxiety of knowing that life doesn't go on forever that we can experience transcendence and get in touch with the infinite. To use an analogy from gestalt psychology, Non-Being is the necessary ground for the figure of Being to make itself known to us. It's only when we're willing to let go of all of our illusions and admit that we are lost and helpless and terrified that we will be free of ourselves and our false securities and ready for what Kierkegaard calls the leap of faith.p. 43
