Greetings Kalamondin,
Returning to your post...Hope you don't mind if I chop it up...I have only brief intervals of time to invest at the moment.
Discussing the quality of Qi...
[[P: Have you heard anything of "quality of chi" before?
Is there any actual documentation on the substance "chi", that you know of?
K: Well, I’ve heard acupuncturists talk of it with different adjectives before: sluggish, hot, cold, damp. I suggest looking at some of the books I recommended for greater detail. ]]
I will try to obtain some of these texts...Thanks for providing that list of references.
"Sluggish" (as opposed to lively, I imagine), which would imply speed, velocity in it's nature..."Damp" very interesting (as opposed to dry, I imagine) hmmm. Hot and cold...temperature...although I've known warm/hot...I wasn't aware of the thought of cold chi .... Perhaps cold hands are not a lack of chi (as I assumed/ or never really pondered before), but perhaps a different quality of chi...
<<Personally, I’ve experienced chi as hot/warm (ginger tea, a friend with a fever, really great sex, the sun), cold (a tree at night, a mossy stone), imperceptibly fine and smooth (my teacher), pulsing (most people have a kind of fine vibration, an oscillating tremor that I can feel when touching their skin), blasting (my cat when frightened and scratching), prickly (a cactus), buoyant (like practicing the form in a very salty sea), sludgy (my head when hung over). >>Kalamondin
Interesting and creative analogies.
I have felt warm water...buoyant.
Electric heat...I guess that would be dry/hot.
I've never thought of identifying cold until your mention...
Electric shock, buzz...prickly?
Blasting? Don't think so...
Sludgy? Maybe.
Fine and smooth...not!

Pulsing...I'm not sure I understand exactly what you mean...
But sometimes when I become absorbed in the form I do note a faster slower rhythmical cycle...Which I am still trying to identify...Any correlation, do you think?
<<I’ve been instructed to remember that the Dantien is more than just that one point below your navel-rather it’s a belt of energy that surrounds you at that level, and as such, extends beyond the body. Have you ever done standing meditation with your arms in a circle and your hands facing your Dantien? As I breathe into my Dantien when I do this, I can feel the chi pushing against my hands like a balloon expanding and my hands move with my breath, floating on that ball of chi.>>Kalamondin.
P: I tried it myself without results, personally.
I can sometimes feel it between the hands...but not at the tantien...yet, anyways.
Although the sensation felt like a bowling ball...I could not feel it with my hands.
I shall have to experiment with this technique more often.
Are these Qigung techniques?
It can definitely take a while to feel anything, just keep letting go of tension when you try this and try to let go as well of the expectation of feeling anything in particular. I would say that yes, standing meditation is a qigong technique…but you will, of course, find it as a part of many martial arts disciplines, including tai chi, as it can help you develop an understanding of stillness, structural alignment, chi flow, patience, perseverance, rooting, balance, quieting the mind, etc. etc. I don’t think it’s necessary to practice standing meditation in addition to tai chi, but it can certainly be a valuable auxiliary practice.>>Kalamondin
Thank you for your advice.
And I agree that Qigong and Chinese medicine are valuable auxilliaries to Taijiquan.
Best regards,
Psalchemist.
