I recently started the active exercises and I was wondering about the breathing. In the beginning excercise Master Li says to take a deep breath, while inhaling pull the stomach in a little and while exhaling push the stomach out. Is this kind of breathing done in all of the active exercises? I tried it last night and I found I was focusing on getting the breathing right instead of energy moving. This kind of breathing feels unnatural to me, since I've been taught to do the oppostite while meditating. Also, I practice zazen sitting meditation and occasionly pure land meditation(reciting the buddha's name). Can this type of sitting mediation replace the small universe meditation? If not, is it ok to mix? Excuse my noobness
