Meditation is an essential bridge from thinking to not-thinking, and difficult to master.
And, ironically so, like drug-use, in that it will prevent arrival at the no-thought zen-state.
There comes a perfect moment to abandon meditation, and only in its abandonment, is the needle threaded, and the goal achieved.
The goal is one-ness, and can only be arrived at by abandoning that as a goal.
No wonder so few achieve it
You have to want it, above all else, and then, at exactly the right moment, not-want it.
