Yin-yang dream meaning is explained below using 5 different sources. Each interpretation is shown with its source.

Interpretation 1 — Betty Bethards

The Chinese symbol for the dynamic union of opposites; secret of changes, life, death and regeneration in the universe. The yin principle is female, creative, intuitive, receptive, dark, negative, body, the unconscious. The yang principle is male, intellect, strength, light, positive, spirit, consciousness. The polar energies are fully expressive in their unity or oneness. We must achieve a balance of the female- male energies within us to evolve from the earth plane. (Note: My guidance includes the creative-intuitive as a combined female energy. Most other systems put the creative under the male energy.) See Female, Male.

Interpretation 2 — Pamela Ball

This symbol has become much better known in the last thirty years in the West as the balance of two complementary oppositcs. In dreams it indicates the balance between the instinctive, intuitive nature of the feminine and the active, rational nature of the masculine.

We arc continuously searching for balance, but not necessarily a state of inertia.

The yin-yang symbol signifies a state of dynamic potential.

3- Perfect Balance is created by the energy created between two complementary opposites.
