If you wish to percieve reality directly, stop reading second-hand Buddhism! Read less, meditate more! Not mumbo-jumbo new-age crap either. I'm talking about methods for experiencing each moment more completely, as in following the breath, observing sensation without reacting, sitting with a big question (What is this?) and the like. You might try the Sutra on the Full Awareness of Breathing. For an online, although wordy and difficult, text relating more directly to your post try

Although not literally accurate, it is an interesting foray into ancient Indian thought and logical methodology. The Buddha discusses the location of mind an sensation just a few pages in, so bear with it. ( I still don't REALLY understand it, and I'm a pretty poor Buddhist, but I am willing to discuss my little interpretations reading-circle style if you want to PM me.)
