The heart always has an object of love; it is always attracted to some sign of beauty. Whatever the heart holds its attention on, it will acquire its qualities. Rumi said, "If your thought is a rose, you are rose garden. If your thought is a thorn, you are kindling for the stove." Being between the attraction of the physical world and the ego, on the one hand, and spirit and its qualities on the other, the heart is pulled from different sides. But ultimately behind all these various attractions lies one great Attractor.
There's a thread you follow. It goes among things that change. But it doesn't change. People wonder about what you are pursuing. You have to explain about the thread. But it is hard for others to see. While you hold it you can't get lost. Tragedies happen; people get hurt or die; and you suffer and get old. Nothing you do can stop time's unfolding. You don't ever let go of the thread.
