When faced with adverse circumstances, if you can do something, do it and there is not need to worry. If you can't do anything, then there is no point to worry. So in either case, worrying is an added suffering. But this does not mean of course that we should not be unhappy about injustice, abuse and other kinds of behavior that brings suffering upon others.

Anyone can be happy by simply training their brain.

The ultimate reason for meditating is to transform ourselves in order to be better able to transform the world.

We cannot study everything at the same time.

Meditation gives you more inner strength and confidence, and if you don't feel vulnerable, you can put that to the service of others. So it's not just about sitting and cultivating caring mindfulness. It's building up a way of being and then using it for the service of others.

If you don't have altruism, inner strength, inner peace, attention, then it's a trauma. It makes a difficult life for you and for others.

You get [something] in your body that is the suffering or the problem, and then you [add] a second one, which is worry. In both cases, [it is] pointless.
