The purpose of life is to suffer. Another purpose of life is to be compassionate to that suffering. The third purpose of life is to meditate.
When we expect not to suffer, to transcend suffering through practice, we end up suffering more whenever we suffer. When we make the purpose of our lives to work with that suffering, we don’t resist so much when the suffering appears again. When suffering appears, we remember to work with it. When it goes away we remember our practice works. Compassion is the practice of working with our suffering to help it pass.
When you meditate, the purpose of life is to meditate. All the rest of the stuff that you do opens up the space to sit with your awareness, in your body, being alive. That is the purpose. Life is the opportunity to experience all of this wonder, and to wonder what it is all about.
