"Lay down all thoughts, surrender to the void it is shining. That you may see the meaning of within it is being." From birth to death all we ever do is think. Even when you are asleep you are having dreams, there is never a time from birth to death when the mind isn't always active with thoughts.

Basically it is saying what meditation is all about. The goal of meditation is to go beyond (that is, transcend) waking, sleeping and dreaming. So the song starts out by saying, "Turn off your mind, relax and float downstream, it is not dying." - George Harrison.
