I'm always a little sceptical about the 'Beat depression without drugs' titles that seem to be all the rage these days. I agree that a lot of milder forms of depression can be solved with a change in lifestyle, exercise, meditation, vitamin supplements etc. For very severe forms of depression (of which I suffer from) anti depressants can literally save your life.
"The original heart/mind shines like pure, clear water with the sweetest taste. But if the heart is pure, is our practice over? No, we must not cling even to this purity. We must go beyond all duality, all concepts, all bad, all good, all pure, all impure. We must go beyond self and nonself, beyond birth and death. When we see with the eye of wisdom, we know that the true Buddha is timeless, unborn, unrelated to any body, any history, any image. Buddha is the ground of all being, the realization of the truth of the unmoving mind.” Ajahn Chah
