The statement from our textbook, "'Love one another' (I John, iii. 23), is the most simple and profound counsel of the inspired writer" (Science and Health with Key to the Scriptures by Mary Baker Eddy, p. 572), makes clear that really to love must be a great accomplishment and require a depth of knowledge far beyond what we have been accustomed to believe. We see as well that Love in itself is profound and simple—profound in encompassing as it does all of creation, and simple in that it is always itself and itself only; that it is pure Spirit or Truth, untinctured by any of the falsities or intricacies of mortal belief.
If we would love, it is incumbent upon us to gain an accurate knowledge of what Love is. What we wish to express we must first understand, and it is in the measure of our understanding of Love that we are able to manifest it. When we comprehend it in the fullness of its spiritual significance, we begin to appreciate how little of it has yet been demonstrated by any of us. The greatness and nobility of character required truly to love, transcend all human standards and emanate from divine Love itself.
In order to gain a scientific sense of it, we must let Love define itself to us, for the only thing that can fully define it, is itself. Love is Mind, Soul; hence the material senses can neither interpret nor understand it. It is that which impels and characterizes all the activities of Mind.
