This is a hard one for me. I can, if I am not diligent in love, easily get my feelings hurt. I imagine that if I am to love others as I should, I may need to nurture callouses where my own feelings are concerned. This might be somewhat true, but more than likely I need true love to grow in me so that the energy of love flows out like a living spring.
