"As long as the dark foundation of our nature, grim in its all-encompassing egoism, mad in its drive to make that egoism into reality, to devour everything and to define everything by itself, as long as that foundation is visible, as long as this truly original sin exists within us, we have no business here and there is no logical answer to our existence. Imagine a group of people who are all blind, deaf and slightly demented and suddenly someone in the crowd asks, "What are we to do?" The only possible answer is, "Look for a cure". Until you are cured, there is nothing you can do. And since you don't believe you are sick, there can be no cure."
One of my firends believes outside scientific knowledge there is probably virtually nothing worth knowing. He is sure we have reached a peak in scientific knowledge (I tell him that that is a trap every scientific age falls for)..
The "problem" for meditators is that once you have taken the red pill there is no going back. Taste the prison bars of the mind that stop us being free and you have also tasted freedom itself. It never goes away, and if you choose to take the blue pill it no longer works.
You have to learn how to swim or you WILL sink back.
You can sink back but you will always know you have.
Desire to be free doesn't lead to freedom, but more trying to get free. Letting go of desire leads to freedom*.
