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.
A hermit must have a deep experience of communion with humanity. Without this, you cannot be a hermit, because you would only be lonely. You would not be really solitary. To be alone and cut off from others would make you very unhappy, but to be alone, and to be deeply united with others, in deep communion, that is a possibility for which many people long. That is what I call solitude—over and against loneliness.
