How can I bring it about?

You can do nothing to bring it about, but you can avoid creating obstacles. Watch your mind, how it comes into being, how it operates. As you watch your mind, you discover your self as the watcher. When you stand motionless, only watching, you discover your self as the light behind the watcher. The source of light is dark, unknown is the source of knowledge. That source alone is. Go back to that source and abide there. It is not in the sky nor in the all-pervading ether. God is all that is great and wonderful; I am nothing, have nothing, can do nothing. Yet all comes out of me -- the source is me; the root, the origin is me.
When reality explodes in you, you may call it experience of God. Or, rather, it is God experiencing you. God knows you when you know yourself. Reality is not the result of a process; it is an explosion. It is definitely beyond the mind, but all you can do is to know your mind well. Not that the mind will help you, but by knowing your mind you may avoid your mind disabling you. You have to be very alert, or else your mind will play false with you. It is like watching a thief -- not that you expect anything from a thief, but you do not want to be robbed. In the same way you give a lot of attention to the mind without expecting anything from it.
