The first explanation of this is that there is no explanation, as Love is its own explanation. Also it is self-explanatory, and without this Love nothing conveyed to the mind will clarify it. At the same time the mind cannot be thoroughly efficient without it. Concentration cannot be accomplished without feeling, without power. When the concentration takes one into this Universal Ocean of Love, it is found to be the essence of the heart stream. Then everything and everybody will be attracted. This living evidence is the only clarification.
