I've never had a problem with sleepiness, and I only get impatient when sitting on my own. But oh *that leg pain is something else*. Does anyone have any advice from a Zen perspective - not necessarily how to reduce the pain, but how to not simply hate meditation because of it (at least the half lotus position, and at least when in that position).

This isn't a Buddhist question per se, maybe better placed in a yoga or Taoist thread but anywhere here I go: When I am in the lotus position (classic right leg over left leg as instructed in all Buddhist guides) for the past 10 years, my right knee has always floated a quarter of an inch off the ground, even if I try to adjust my position by sitting offset on my mat. Anatomically speaking, I don't see how anyone can have both of their knees on the floor.. Although I feel energetically blissful whilst maintaining the posture, the posture feels uneven, imbalances my torso, and I feel uneven pressure on my right thigh and must end my lotus posture in about 10 to 20 minutes due to the pressure on my right thigh... Sometimes I switch reverse full lotus and that makes me feel more balanced. Am I doing something wrong or is this something all advanced lotus meditators must deal with? How can I remedy, deal with, compensate (et cetera) my lotus posture? Also, this is a separate question but are there any passages in the canon that speak about posture? Any suggestions in any realm, physical, environmental, or even mental are welcome.
