Hiya, bro. I'm too lazy to post the stuff myself. Well, there is way too much out there. Here are some of my favorite links to magus info/forums: astralpulse.com (covers all sorts of stuff--almost everything a mage would love to learn) chaosmagic.com psipog.net (for energy and psychic-related material only) Look through the sections labled "articles". You will find tons of useful information. (NOTE: "ki" will often be referred to as "psi" or just plain old "energy".) Sorry about the laziness. I hope this is kind of what you're looking for.
Try checking out Aikido. Certain schools of Aikido give a great deal of time to development of Ki and the exercise of it.
