Making peace with ourselves means accessing inner peace that can be cultivated and extended to others. Authentic inner peace does not mean living in isolation, but discovering our own true nature and living in harmony with other people and the environment.
Each of us is a soul. We have been told that we "have" a soul, but that's not the same thing. To have a soul would indicate that we are primarily an ego or a personality that in some way "possesses" a soul. Our essence IS the soul and all aspects of ego and personality flow from that essence. At its core the soul is pure, but habits, tendencies, and imbalances often obscure some of that inner light. Our spiritual work is to correct whatever shortcomings may be preventing the light of our sould from shining through.
