Let me quote a paragraph in the article that makes it clear that the author is not talking about surrendering one's will to another human being, a baba or guru, or letting go of coping mechanisms of faith. In fact the opposite is the case.
Letting go is a trait I am committed to cultivating. The vulnerability of acknowledging what is already true. That in admitting I don't have much control of anything really, I can let go of the stress and anxiety that block me from experiencing the beauty in life. And that faith is what I really have. A faith in those around me and that even when things are scary and it appears the world is crumbling it rarely stays that way. Our lives and our souls naturally gravitate toward the light. Toward life. Thya h'matim the revival of the dead. The revival of hope. Of possibility. Of redemption.
This is a view that is close enough to make for good interfaith dialog. What are the similarities and differences? I don't see the essay as challenging good sense, piety in a different faith, mental health. It really deserves a second chance.
