I think it is not necessary to split the energy. As I see it, we move the energy throught our two main channels. The back channel and the front channel.
As I've understood from one of the CD's if the energy is blocked in the main channels also the other channels will not get the necessary energy.
As I see it we are as a tree. Our main channels represents the trunk, the other channels the branches. If the trunk doesn't has enought energy also the branches will not have enough and at the end they will die. The tree too. The same for us.
When the energy in those two main channels is enough, from those two channels the energy will go to the other energetical channels which further will provide the needed energy for the organs, also for the kidneys.
That is as I see it.
PS: Sorry for my english if something is not written ok. I am not an english speaker. I live in Slovenia (former Yugoslavia, now Europe).
