I usually say a couple of things about this. First, Zazen ... and all the world really ... is just what it is, but the judgement about the situation is right between your ears. It is you who judges some situation good or bad, complete or incomplete, but the situation is just the situation. Same for Zazen. If you can come to feel it complete, whole and with the other characteristics I describe, it is. If you feel it incomplete and lacking, it is. Otherwise, Zazen is just Zazen. Who judges it incomplete or that the world is not whole but you? I call it thus a "non-self fulfilling prophesy."
Zazen has some similarity to Tibetan esoteric visualization practices in which the meditator envisions themself as a Buddha, so comes to embody the characteristics of that Buddha. Likewise, Zazen. A friend of mine who is a Broadway actor told me that he assumes the role of Hamlet until he becomes Hamlet. So, I recommend what I call "non-method" acting ... act the role of someone sitting with total trust in the completeness and wholeness of sitting, until the role takes one over. If you instead play somebody who feels that Zazen is lacking, then it is lacking.

We sit vibrantly, with sincerity and dedication ... yet there is nothing to attain. We sit, letting thoughts go, but neither do we run away from thoughts. We come to see the Light of clarity and wholeness which shines through both thoughts and no thoughts. We sit in radical equanimity so equanimious that we even feel equanimity about those times of sitting when we do not feel equanimious. We trust. We sit.
