Master Lin says to allow 30 minutes between doing different energy systems.
I often do yoga stretches I've learned (thank you Paul) before doing the SFQ active exercise early in the morning. However, I do not treat them on and energy level, just at the physical level.
Now since everything is energy ..... I am doing some energy work but I believe that it is the conscious involvement in an energy system that Master Lin is talking about. Otherwise it is impossible not to engage in energy work before or after SFQ.
You are perfection.
