Do everything with a mind that lets go. Do not expect any praise or reward. If you let go a little, you will have a little peace. If you let go a lot, you will have a lot of peace. If you let go completely, you will know complete peace and freedom. Your struggles with the world will have come to an end.
Holding on to anything is like holding on to your breath. You will suffocate. The only way to get anything in the physical universe is by letting go of it. Let go and it will be yours forever.
The mind is like a river. It can flow in two directions. It can lead us either to freedom or bondage.
