Sati is life. Whenever we don't have sati, when we are heedless, it's as if we are dead.
You should think about your own death 3 times per day at the very least.
Happiness and suffering do not depend on being poor or rich, they depend on having the right or wrong understanding in our mind.
If you let go a little you will have a little happiness. If you let go a lot you will have a lot of happiness. If you let go completely you will be free.
