So, what are the available alternatives, then? Is it one of the those things where you sit for nine years gazing at the wall and then enlightenment comes? Are you suggesting koans?

I think if you care about the truth, THE ACTUAL TRUTH you can diverge time and effort into it depending on your own situation. The illusion of rationality will help you, by observing as many variables you can similar to a General on a battlefield, for the long-term victory.

Of course, the truth is already as it is, it's only an illusion to not become aware of it, it's as if you are watching a visual illusion, and suddenly you see the other perspective and it was what it was.

That is highly unlikely -- otherwise you wouldn't be able to operate in reality.

From the perspective of arational reality, you're fine to be rational as long as you are aware. It's as if you say before every equation "I am aware this is a human projection" yet you remove this paragraph from the equation OF the equation because it's too obvious.

If you didn't operate in reality people would come to you and ask, what are you doing? If it was thousands of years ago, people would say "I want what you have" and those who didn't operate in reality says "You came to me"
