This seems to me to reflect the distinction made by Jung between the self (here RH) and the ego (here LH), fulfilling different, but necessary, functions. For him, the self is the product of psychic integration over time and unites conscious and unconscious processes, while the ego is that part of the self identified with the conscious will, and which, though necessary in the earlier stages of development in order to anchor the growing individual in the world, comes to be transcended in the process of spiritual growth.
