You can never love another person unless you are equally involved in the beautiful but difficult spiritual work of learning to love yourself. There is within each of us, at the soul level, an enriching fountain of love. In other words, you do not have to go outside yourself to know what love is. This is not selfishness, and it is not narcissism; they are negative obsessions with the need to be loved. Rather this is a wellspring of love within the heart. . . .
If you find that your heart has hardened, one of the gifts that you should give yourself is the gift of the inner wellspring. You should invite this inner fountain to free itself. You can work on yourself in order to unsilt this, so that gradually the nourishing waters begin in a lovely osmosis to infuse and pervade the hardened clay of your heart. Then the miracle of love happens within you. Where before there was hard, bleak, unyielding, dead ground, now there is growth, color, enrichment, and life flowing from the lovely wellspring of love. This is one of the most creative approaches to transfiguring what is negative within us.
