THE PERSISTENT ILLUSION
The only "decision" thought/ the "me"/ the self can make regarding UP/Yoga/Dhjana/Zazen which it does not know, cannot "know", and will never "know" (thought can "know" only a description, a definition, words and symbols), is not to even be silent (which thought cannot decide upon obviously) but to not re-act, let go, suspend doing anything at all, and suspend language. THAT means an all-inclusive observation and silence. But it's not that the self that starts it (its supposed "last decision to start UP").
If UP should not be just more of the thought-hypnosis, the observation naturally MUST be all-inclusive and unbroken, flowing. There cannot be any sense of a division in it (the horizontal conflict of subject-object), no sense of control, expectation or effort, which is all again the "self", produced by thought.
So yes, the observation IS indeed "all" inclusive (as one unitary movement) but it's NOT more effort, expectation and it's not another (positive) goal that is set by thought to pursue.
UP is not a "leap" (a positive action), it's a negation of the whole mechanism of thought.
The "me" cannot "leap" anywhere, including to UP because there is no "me", it's an illusory product of thought.
Nothing per se is "started" or "leaped to". The Universe is always already here, no need to make any jumps! Where would be the jumping to? That what is is all there is. David Bohm said, quite correctly that "all that can be is what is". Nothing is separated from It.
This need to pursue a goal (what is - the Reality vs "what should be" - an ideal) is a persistent illusion/hypnosis/conflict produced by thought - the Horizontal Conflict, time and the "self".
So what really happens is that in the Simplicity, the One unitary Reality, thought produces the persistent ILLUSION of separation and the need to "do something" to "return to reality", which means a pursuit of just another goal, the horizontal conflict, hypnosis and the "self" with its fragmentary perception.
