Awakening, the Void, nothingness, whatever you want to call It....

Its only a goal, destination, or end result, until you reach it,

and then it is a way point of sorts, between who you were and who you are.

Its what happens with you after you find out who or what you really are that matters.

Which I suppose means there is no end.

Once upon a time, when I would stop the internal dialogue and just breathe, it would feel like my body was relaxed but my head felt like a brick.

Then I learned of some Yoga relaxation exercises that prevent cramping or whatever.

Tensing and releasing muscle groups one at a time, and then the whole body all at once. 

First legs, tense them up for a few seconds and then let the tension go.  Then arms, torso, scrunch up shoulders and neck, and lastly face.  Then the whole body all at once. This has the effect of releasing tension that has built up in the muscles. 

Then assume your usual meditation posture.  For me:  lying on back, arms at sides, fingers to thumbs, feet elevated is better, no pillow for head preferable, motionless, silent....

This was back around the late 70s early 80s.  I had been planning to build a Sensory Deprivation Tank, but found with these exercises I didnt need one.  After a few minutes I could no longer feel my body.
