Excuse my ignorance, I'm still finding out about the Theravada. I've heard many people mention the 'Vipassana traditions' as though they are different from Theravada traditions, can someone clear this up for me. Are the Vipassana traditions more secular than Theravada? I went to one of these Vipassana meditation sittings, and although they say they are primarily theravada I noticed a lot of mentioning of Zen and certain mahayana sutra's also.
"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
