I either practice in silence or with Spring Forest Qigong music. I've practices so long that it is much, much easier to go into the emptiness with the music. You know the old "bell rings and the dog salivates?" Well, the music plays and I slip into the emptiness.
Chunyi says some people become bored in the early stages. As they begin to open their channels it takes more and more energy to fill the channels and it takes more time to feel the energy, which could be boring. After a couple of weeks, however, the reservoirs are filled and you can feel the energy again quicker and fuller.
A woman called in today saying she has felt tired after beginning her practice. Chunyi says that some people need more sleep, and that Qigong practice brings that out.
Keep practicing. I'm heading upstairs for an evening meditation as soon as I brush my teeth.
