The light comes on of its own volition, of its own accord. "The light shines in the darkness"--John "The darkness is the cradle of the light"--Rumi "In the darkest moment, the light comes on"--Campbell The darkness discloses, reveals, exposes the light. Sit in the right kind of emptiness, stillness, silence, (darkness), waiting, long enough, and the light will come on. "What light is that?" you may wonder. "The light that lights the way." All the light that has ever been, or ever will be, is just this way. Light upon light, the gateway to realization and new life. Light begets light. And it all starts in the darkness. Believe in the darkness. Believe in the light. Trust the darkness. Trust the light. Trust yourself to know what's right when you are evaluating paths, and when you meet it on the path. Even if it is wrong, it will eventually lead you to right. Keep trusting the darkness to carry you to the light. The darkness leads to the light, the light leads to the way. That is all we need to take on faith. That is all we need to know.
Here is a link to “The Nature of Spiritual Reality” in A Handbook for the Spiritual Journey on my Jim Dollar’s Published Works site:
We know it when we see it. The path that is our path (And everything associated with it). No one can hand it to us or tell us what it is. Realization is a personal matter. It comes in its own time, in its own way. It can be ignored, refused, rejected, but it cannot be conjured, compelled, created. Our role is to know what we know, look at everything and see what we look at, ask the questions that beg to be asked, say the things that need to be said, and wait, wait, wait for things to fall into place, in an "Oh, I get it," kind of way.
