In my experience, all our problems do indeed stem from this hyperactive and delusional thinking we have acquired over time.
There is a way to eradicate the light-speed, blind reactions and the habitual confusion. The way is very simple. It boils down to just two words: do nothing. That’s it. Do nothing. Sit quietly in a room alone and do nothing. Watch the monkey mind and do not try to fix it or eliminate it or drown it out or engage it.
This is doing non-doing. Observe the mind, on autopilot as usual, screaming editorial comments from the sidelines like some frenzied play-by-play announcer and do nothing about it. Don't turn the monologue into a dialogue. Do nothing. “Nothing to see here, folks. Let’s keep it moving.”
