Colin,
Very happy to hear your self practice is going well. Interesting for me to see what I wrote back in October! There 'are' some underlying consistencies or truths to a qigong practice, and also, many possible ways, creative ways with the practice as given, to progress through seeming roadblocks.
I don't have a sense of how the pychology of your thinking came into play, although I would still say that any anticipation, good or bad, is extra energy you don't need. I realize you just are sort of moving past this,,,reflection is useful. Going forward, really let this all go and give yourself to the practice focus's, minus any story surrounding it. We sometimes tend to think of extra energy as just relative to physical blockages, not something like anticipation.
Although one can start , I believe, in level II, which moves more focus to the heart level, beginning with level I, and moving on to level II, has a nice grounded progression to it.
Love,
Gallen
