Mastering – or, if you prefer, integrating – the psyche is the work of a lifetime….This mastery is not holding the psyche in rigid subjugation (which is impossible in any case), nor is it a matter of having a maniacally religious ego lording it over the emotions and the body. Rather, it is being centered in the still, small voice that is the true 'I' of the spirit.
