what are 'yang' and 'yin'?
Answers
In Chinese philosophy yin and yang is a concept of dualism
Answer:Yin-Yang is important to humans in the mystical contemplative life of spiritual awakening. And I state it that way for a reason, namely, yin-yang is a special mystical event of the awakened consciousness which means that the person is already mature in the spiritual life. So I do not see that yin-yang is important to the beginner who is just starting out on the way of perfection. But it becomes important for the mature mystic.
Its importance is as simple as it is repetitive; for it shows the mystic, in its repeated appearance in the depths of the Soul, that God and Soul are United to one another and, in fact, that they have become One Thing Together.
The yin-yang, the black-white, encircle one another and spin about the single axis of being which their union forms. They actually slowly start up in a counter-clockwise spinning motion, and then speed up in a dizzying spin about one another in an extraordinary celerity, and then immediately vanish into the depths of the Soul.
The Soul sees the black-white purity of God and Soul which are distinguished from one another but are not separate from one another. Thus they form the Monistic Duality that is the Mystical Oneness of God and Soul which constitutes the Estate of the Perfect, or the spiritually awakened saint.
The yin-yang also manifests itself in a truly massive consciousness of the Divine White Light of Life infusing the Black Opaque depths of the Soul, such that the Light of God Illuminates the Darkness of the Soul. This Illumination changes the Soul into the Light of God. Now the Light of God is God Himself. So the Soul's Illumination or Enlightenment is the Soul becoming God.
The yin-yang also manifests massively in God's Indwelling and Inhabitation in the Soul as the Black-White Triune Ocean of God. The Soul gazes inwardly into the Triune Ocean of God which is the Black-White Light of Life of the Godhead who has made His Home in the Soul. Thus the Soul is the Basin of the Triune Ocean of God, the Ocean of God that is the Three Seas of Divinity Living in the Soul in the Black-White, Yin-Yang of the Fire and Water of Life.
The yin-yang, therefore, concerns the life of the wayfarer, the life of the journeyer to God in its perfect spiritually awakening and awakened state.
However, in the Beatific Vision of the absolutely perfect, the yin-yang does not appear; for in that Vision of Visions, there is only the Diamond-Gold of the Subsistent Godhead-Triunity which is Transinfinitely above the black-white of the perfection of the wayfarer.
