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.
There are times not to answer the door, not to answer the phone, not to do undone things, but to rest in silence from everything. The world can wait for five minutes. In fact, no matter how busy we are, no matter how well organized, no matter how little rest we allow ourselves, we will never do all that needs to be done. But to do well what we are called to do, it is essential to nurture a capacity for inner stillness; such quiet, deep-down listening is itself prayer.
