So I was looking for the characters for one of my names (this according to Pharmako/dynamis, this according to WWWJDIC), and ran across this. According to Pharmako/dynamis, makyo are "visions that appear at certain stages of the meditation path" and that "these visions are harmless, even excdellent, progressive stages, unless the practitioner believes that they signify complete attainment".
Heh
