Thanks. Hope you don't mind if I add one observation. The idea of sitting in lotus position is not universal. Indeed, Taoists prefer sitting on a chair to free up the legs. Most westerners will find it difficult to sit cross-legged without discomfort. This may become a barrier to meditation. It doesn't have to be a barrier - just search for "taoist microcosmic orbit" and you will see what I'm talking about. :-)
