Can Anyone Separate the First Two Energy Bodies?

Has anyone gotten to the stage where they can clearly separate the first two energy bodies?

I’m not talking about being able to simply feel both the physical and etheric bodies. I’ve been able to do that for years. I mean that you can feel how the etheric permeates the physical body as well as extends beyond it and you can work with them separately as well as in coordination. I’m starting to work with this in the double-palm change as well as in Tai Chi. In Tai Chi this seems to facilitate the covert level of Peng, Gi, Lu, and An that Bruce mentions in his Power of the Internal Martial Arts book. In both, opening and closing gets more complicated because you can either open or condense either body.
