A lot of spiritual advice takes the form of people telling us what we need to do to be happy. We need to love everyone unconditionally, let go of stress, drop the worry, and forgive. I find this advice frustrating, because it tells us what we need to do, but stops right there. At step one. It does not tell us how we can reach any of these states of being. How do we reach unconditional love for someone we currently cannot stand? How do we let go of stress when the conditions causing the stress are not going to go away? How do we forgive someone who has deliberately caused us excruciating pain?...
