The saddest thing in life and the hardest to live through, is the knowledge that there is someone you love very much whom you cannot save from suffering.
Do not be a bodhisattva, do not be an arahant, do not be anything at all. If you are a bodhisattva, you will suffer, if you are an arahant, you will suffer, if you are anything at all, you will suffer.
To have a body is to suffer. Does anyone with a body know peace? Those who understand this detach themselves from all that exists and stop imagining or seeking anything. The sutras say, "To seek is to suffer. To seek nothing is bliss." When you seek nothing, you're on the Path.
