Direct experience

Direct experience generally denotes experience gained through immediate sense perception. Many philosophical systems hold that knowledge or skills gained through direct experience cannot be fully put into words.

You cannot grasp it; Nor can you get rid of it. In not being able to get it, you get it. When you speak, it is silent; When you are silent, it speaks.

A good start are the audio books by Alan Watts

Note: Words only provide reference to experience. They are not the experience they refer to. The reference can be quite exciting though.
