To have faith is to trust yourself to the water. When you swim you don't grab hold of the water, because if you do you will sink and drown. Instead you relax, and float.
Every single being, even those who are hostile to us, is just as afraid of suffering as we are, and seeks happiness in the same way we do. Every person has the same right as we do to be happy and not to suffer. So let's take care of others wholeheartedly, of both our friends and our enemies. This is the basis for true compassion.
To ride a bicycle properly is very like a love affair-chiefly it is a matter of faith. Believe you do it, and the thing is done; doubt, and, for the life of you, you cannot.
