thanks to all who replied

i understand the replies but i have a question

i have been told by several people that active or motion qigong is safer than quiet or meditation qigong

that a person can experience severe side effects if the meditations are not done properly

therefore i was under the impression that the motion exercises may be more easily mixed

also i have some friends that say tai chi, martial arts, and other motion qigong exercises build on each other

in short, it seems that it is ok to mix the motion qigong exercises but extreme care should be taken with the quiet qigong exercises

i have tried to mix the spring forest motion qigong with other motion qigong exercises, meaning that i practice other types of motion qigong, and it seems to be ok

on the other hand, when i tried to mix the meditations i became nauseated

any comments?
