As we grow from infancy to childhood, to adulthood, to old age, we move to different levels, different planes of existence. Physically, mentally, and psychologically, we change. The way we pick up signals, the way we relate to the world, what we do, changes. But the same love is manifested at every period of our life. Our capacity to receive love changes. Our capacity to respond to it changes, but the same love is constant. We see the same love present, for example, in the simplest organism – the life of a single cell. We see it, the same love at work, in the power of sexual attraction throughout nature. We see, the same love involved in the meeting and the marriage of minds, persons; and we see the same
love fulfilled in the union of hearts.
