I don't think you lose control of your bodily functions for a bit and cessate life. It's probably more so you become aware of those processes ongoing in your physical body and soul which keep you alive and can actually utilise your consciousness to properly empower them in lieu of their potential of death and ending(being now fully aware of their cycles, as cells die too.) You can use your awareness of this now to direct energy in a specific way within those processes ensuring unceasing life, a bit like programming some really powerful software that recharges itself or something- definitely would take a while but totally worth it.
