Thanks for your replies. There is a Sri Lankan Vihara centre near me which I've been too, I've also practiced Zen, though I don't know if it's right for me. I've voiced these concerns on this forum before, so no need to talk about it now.
"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
