Reading Undoing Depression right now.

Depression is described as what I feel a Buddhist would call wrong view. That understanding of it helps me not totally reject psychology of spirituality, or totally reject spirituality for psychology. Psychology is about views. A psychological disorder is wrong view.

And so when I'm agitated with someone, when I feel oppressed by them, when I feel they aren't attuned or they're ignorant and taking it out on me, I don't have to express my frustration to them. That would be a certain psychological path. But something in me doesn't feel that it's right. (Maybe that's still a result of being in the depressed view of lack of self-assertion, I don't know.) But I could also use that as a prompt to remind me that I'm in the wrong view, and this reaction is coming out of being in the wrong view.

Given this understanding of depression, it would be very interesting to think about why exercise can have such an impact. I would think that the body is a huge determinant in what view we hold. A sick body, by default, leads to a sick view (of course it can be overcome and doesn't apply to all people etc.)

Dancing especially would train new physical and emotional patterns in the body and thus the mind.

"That the patient is in a state of spiritual despair is due to the fact that the astral body cannot make use of the physical and the etheric... is only in the evening, when the physical and etheric bodies are tired, that their normal union with the astral begins to take place. Therefore the patient becomes properly awake in the evening. This whole condition indicates that it is necessary first of all to strengthen the astral body in its activity. This can always be attained by giving arsenic internally in the form of a mineral water."
