The soul has to be connected with the body. So it has to bear consequences. That means the master of the house has no control over the household, and has to bear the consequence. The ego won’t ever do that. You just have to practice more, and then learn from experience, or from sheer will power, or spiritual power, to subdue it, the ego. Then the cells will be gone, the physicals cells or the ego cells will just have no more room to exist in your life. Then the soul will take more control, and make better decisions, and then better, better all the time.
