I have. Read The Power of Now. My gas was cured before I did, but the book reaffirmed feelings I had been having for some time and articulated them very well.
Cliff notes:
1. Lots of psycho babble b.s.
2. The endless pursuit of material wealth/success/possessions will only bring with it more suffering and misery
3. Nothing lasts forever (see above)
4. The only true peace/happiness in this world is accepting who/what/where you are, right here and now
5. You are not who you think you are
6. You are enslaved by a mind that you can’t turn off, that is incessantly thinking about the past and future, judging yourself and others and you’ve come to identify that mind and those thoughts as being you (see above)
7. All of the above reinforces the fact that all you really have, and all that really matters is the present moment, and your relationship with it.
When was the last time you ate a great meal and felt satiated? Like that great meal was enough and you weren’t immediately looking forward to the next great meal you might experience?
Happiness or contentment that is conditional upon materialism, future experiences, etc. is a fools errand.
