Duality - that is, two-ness - is a general feature of Creation. It is the law of sex all through the animal and vegetable worlds. It is beautifully expressed in the response of Parallelism in poetry, especially the Eastern poetry so fully illustrated in the Holy Scriptures: [Scientific Basis and Build of Music, page 41]
