I guess my question is sort of related to this "tongue needing to touch the roof of the mouth" thing, and I understand what you are trying to get at, Gallen, but for a beginner at Qigong (yet quite experienced in other forms of meditation), I'm having difficulty with this one particular area.
The reason: I wear dentures. They definitely would pose a blockage to the free flow of energy, I would think. I asked a friend who is now in level 2 and they indicated just to think of it in terms of "good, better, best", but I'm wondering if it would be better/best, to get the proper "contact" that I remove my dentures while doing the Qigong meditations and exercises. I'd not have a problem with it while doing them alone - just if I were to attend a retreat later. Still, some input from the more advanced on the relative, or not relative, importance of this, would be very helpful.
Thanks in advance.
