attention to the chest region (sometimes as low as the solar plexus) is a common theme in thai and burmese insight practice, found not in all styles but in large enough number to be note-worthy. my teacher when i was a monk, ajahn ratt, teaches several methods of vipassana he developed himself (all of which i can vouch for in regard to their efficacy toward developing insight into the three characteristics), and several of those methods involve pounding it out at the chest. ive been meaning to write up something about his uncommon methods, as they are the sort of stuff you dream about your very own mister miyagi or whatever telling you to do. in place of that for now, i'll spell out one in brief:
- the technique of turning/revolving attention-
attention to any phenomena/sensation. then attention to the knowing of it, at the heart/chest. then attention back out to an 'external point' in the world (pick anything, a thought, a sound, a bodily sensation, etc), then attention back to the knowing of it, at the heart/chest. again and again, faster and faster, whipping around and around like a supercollider or a centrifuge or a vortex, or an orbit. your sitting body may or may not rock with it too, thats ok, dont worry about it and dont interfere with it (the idea being of course to only give importance to the meditation itself so as to energise it as much as you can, cos you need all the momentum you can get).
eventually it will either get so fast and so intense it becomes unbearable and shhhhripp!, (entrance through suffering door), or it will eventually fade into a tiny pulse, or perhaps not even that, and eventually, bloop! (impermanence or no-self door). the first case ajahn ratt described as 'the mind being torn from the heart'; the second, he commented that 'the mind has become weary of the gravity-pull of desire, and wearing down its attachment, is finally severed from it.'
