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.
The inner self is as secret as God and, like God, it evades every concept that tries to seize hold of it with full possession. It is a life that cannot be held and studied as object, because it is not "a thing". It is not reached and coaxed forth from hiding by any process under the sun, including meditation. All that we can do with any spiritual discipline is produce within ourselves something of the silence, the humility, the detachment, the purity of heart and the indifference which are required if the inner self is to make some shy, unpredictable manifestation of presence.
