I actually have some questions about this subject, as I'm still figuring out where/how to start with it. I think I'm beginning to grasp the varied benefits of actually making the effort so (finally) have some motivation to work with, but I've kind of drowned in the SnR of poor-quality information out there.
My interest in meditation is somewhat indirect; IIUC, it's an apparently-necessary stepping-stone to energy perception/study/work, becoming aware of the process of falling asleep, and trance states, three subjects I've been extremely interested in for some time, but which (like meditation) I have no idea where to start with. My attempts to figure and figure them out intuitively haven't really gone anywhere concrete either (...yet).
If anyone has any pointers on studying meditation to the above ends (and particularly if you have any ideas/advice about the things I've mentioned!) I'd love to hear whatever you have to say (email is cool, but I might take a while to respond).
I've actually wanted to ask this on HN for a little while now, but a thread for such topics would... well I don't think it'd be squarely kicked out, but it likely wouldn't be voted up too high.
