Self-perfection will take you in the opposite direction of your spiritual path.
Why…one might ask? Because your seeking to perfect the wrong self. Trying to perfect the body, the mind, intelligence, the ego, emotions, etc, are all things within the world of duality. These cannot be perfected.
The body is either constantly growing or deteriorating in some form or another. You can’t perfect it. It’s in constant change. The mind, you really don’t want it to stop thinking or be quiet. It’s the function of the mind to think. Intelligence we all are born with a unique amount to help us on our journey. Constantly trying to learn more is just a distraction. Ego is not something we try to get rid of. It’s an important piece of our makeup. It helps us be balanced. Emotions are good barometers. The self is just that. A part, not the whole of who we are.
Our Higher Self is what we want to tune into. That brings balance. It also gives us direction and intelligence to work with the body, mind ,intelligence, ego and emotions, etc.
I’ve often heard it said…”trying to perfect the body, mind unit (body, mind, intelligence, ego and emotions) is like wrestling with a pig in the mud.” Two things happen: you get dirty and the pig likes it. The same with the body-mind unit. It loves when you wrestle with it (try to perfect it), master this and it always has something else that needs fixing.
