Meditation is profound.  It is mind and it is essence.  So then, meditation is not a verb.  It is the way mind is.  That's why in Zen they call it the natural state, which means that you don't have to go and do anything to meditate.  In effect, a person who is trying to meditate is doing something that's impossible since meditation is not an action.  Yet at the same time, if you don't do something, you know you're not going to be meditating.  That's the catch-22 of meditation.

In the Zen monastery we used to pound people on a regular basis whenever they thought they understood anything.  If you think you understand, obviously you don't, since mind is by its very essence qualityless.  In qualityless, things are not understood.  You can't understand.  You can't understand since there's nothing to understand and no one to understand, and understanding itself is a quality principle that is invalid.  This is why not too many people meditate.  Or if they do, they do TM, which is simply repeating a mantra over and over - that has nothing to do with meditation.

In other words, they practice some form of meditation that is simplistic and not really meditation.  It might someday lead to the awareness of meditation.  Ah!  There's the key phrase - the awareness of meditation, the awareness of mind.  We're in the Wonderland and sometimes a thing is the way it appears to be for a few minutes, and then it changes into something else.  Nothing is the same in the world of mind.

At best we can say that mind does not have qualities.  And what it appears to have as qualities --- it's confused, it's identifying itself with something other than mind.  That's not up for debate, it just is.  If you debate the issues and the principles, that's great, but you just get caught up in more qualities and there's no meditation.
