Whenever our heart opens to another person, we experience a moment of unconditional love. People commonly imagine that unconditional love is a high or distant ideal, one that is difficult, if not impossible, to realize. Yet though it may be hard to put into everyday practice, its nature is quite simple and ordinary: opening and responding to another person's being without reservation.
Just as each soul spark of every living cell in our bodies makes up that which we call our soul, so too do all living souls in the world cumulatively make up part of a universal soul. Indeed, mysticism teaches us that the soul giving us vitality is connected to, and draws sustenance from, a universal soul.
