"Regarding this Dhamma, it is not something that we can simply talk about or take another's word for it. We need to develop meditation so that the understanding arises clearly within oneself. It is not the case that merely by listening to another's explanation our defilements will disappear. When we gain some understanding we need to chew on it again so that we see it for ourselves with certainty: paccattam."
-- Ajahn Chah
