Confused about location of the sub navel storage center and navel chakra

[dlj92]

Hello all I am doing Robert Bruce's New System. I am currently confused about the exact location of the sub navel storage center. Whenever he describes it seems that it is in the same spot as the navel chakra, and i don't want to stimulate the navel chakra by doing the full body circuit. Can anyone give any insight into the location of the storage center and the chkara.
