Once their soul space opened, the soul, which had absorbed the mind and become one with it, separates from the brain and heads to the soul space where it can freely display its power.
Some special cases like Orion are born with their souls already within their Soul spaces and minds already fused. It'd be biologically impossible for nature to create a physical brain made of matter and flesh that'd be able to house Orion's soul, even if dormant and sealed.
Once in the soul space, the cultivator has to form their sea of consciousness.
This would be done through their newfound connection to their own spirituality which would allow them to sense Soul Force, and Psyonic Force.
Soul Force was the equivalent of the Flesh and blood of the soul while Psyonic Force was the stamina and edge of the soul, the two worked together in perfect harmony to enhance the soul's abitlies.
