What is the heart without Love? It is like an ocean without water or a garden without flowers! Book 10 begins a trilogy within The Teaching of the Heart series that sets the note of Love pouring forth the currents of Dao to fulfil the task of the present Solar System — which is neither knowledge nor information but pure Love. Yet at the same time great cosmic mysteries are revealed between the lines to every sensitive heart. Through the beautiful interweaving of prose and poetry, the Lord of Love and Compassion together with His Beloved declare their Love for each other, as well as for all humanity. Representing the Masculine and Feminine Principles, or Spirit and Matter, these two loving Hearts merge into a single whole — the Sun of Love. Thus their mystical union in the Heavens gives a most powerful impetus to the future unification of all human hearts.
