Forget about "not knowing." Not knowing is actually your natural state. Go take a walk in the garden, look at the grass, the flowers, the birds. You do not know anything about them. You do not know how or why they are.
You already know that scientific reductionism is sterile. One answered question brings up ten new ones. Each answered question opens the door ever wider to what is unknown.
You are already prepared for the next moment. When driving your car on a country road unfamiliar to you, without even thinking, you go left when the road turns left, and right when it goes right. You slow down for the unexpected deer.
You can know a lot of things. The earth is no longer flat. All your knowing is tentative. Labeling and defining helps one maneuver, but does not define what is.
Trying to get rid of knowing is an ego trip. The bars just changed from black to white. This kind of effort is not needed. Ask, who is doing the undoing? Slip into the background and just watch.
Acknowledge that all knowing is tentative. Only a fanatic holds onto beliefs as if they were crucial to life. Only a fanatic would insist on not knowing.
Not knowing is the actual state of affairs. Awareness is always present. It accepts belief and non belief. It accepts knowing and not knowing. Where your mind goes, it is already there waiting.
Awareness is already present, open, ready, willing, without prescription. It is prior to your knowing and forgetting. Your definitions and labels, useful or not, are pointers only.
The body-mind is a vehicle only, roving the field. What it knows is useful to it, or harmful, but all its knowing is temporary and subject to change.
Just step back from what the body-mind sees, and thinks, and feels. You are already awareness which doesn't know. See this and you need no longer worry about knowing or not knowing.
Awareness doesn't need to know anything. That is what you are. Forget about knowing or not knowing. You are prior to that.
