Hi Seedling,
I would say, that more people miss the point, that growth comes, healing comes, through the practice and experience of qigong. There is alot of useful information to take down at the classes and retreats. You can continue to advance , through your self practice. You can become very advanced your practice.
Take one active exercise, and do it twice as long. Try slowing it way down. Do a longer meditation here and there. Try a simple fast, or eating lighter. Try working towards a higher level sitting postion ,,,etc... You can intensify or deepen, your practice, or practice experience.
love,
