The Earth is like a Mother - powerful, creative, the place from which life issues and that which nurtures life and sustains growth. Mother Earth is a wise teacher, instructing all of life in the virtues of balance and harmony, and teaching us about the apparent chaos of destruction which assists new growth, new beginnings, and facilitates change. She brings difficult lessons about the transient foundation of existence.
The Sky is like a Father - strong and encompassing, serving to protect the Mother as She feeds life, offering strength and comfort and the orderliness of boundaries and shelter which She uses to create, grow, and change. He brings the necessary provisions to serve Her purpose, holding a place of order for her processes. And, yet, He owns His own power, holding true to his own motions and courses, balancing order and chaos between the outer and inner realms with graceful wisdom.
And how did these two become themselves and become unified? The Grand-Parents.
The Sun is like a Grand-Father - warm, wise, strong light. He has seen many changes, turned many Seasons, and offers courage and grace to the Mother as She works. There is fortitude, power, aggression - all held wisely in equanimity, progression, patience, and brilliance. And, there is great, good humor - vitality, laughter, and gall - in His honest nature.
The Moon is like a Grand-Mother - moving steadily the ebb and flow of the Great Within and the Great Beyond. She reflects in a gentler way the wisdom of the Sun, enlightening the dark corners and deep shadows which scatter under the Sun's brightness but may be found (like a playful game of hide-and-seek-and-find) in Her silvery glow of compassionate understanding. She tends the Mother through Her phases, knowing intuitively what to do and when to do and how to do. She serves to facilitate the motion of the Mother's creation.
As we humans don these sacred titles - or associate them in our explanations of our place in the Universe - we need to recognize the awesome power and responsibility and accountability that we have wearing them. We use them as a way to define roles and lineages within family and societal structures. And, the manifestation of Divine Masculine and Divine Feminine, or ultimate Yang and Yin respectively, shifts and changes with each person's individual life and character and nature. Thus, these characters take on new meanings - and some role model or mentor or counselor appropriates the mantle of that energy in our spirit and mind. But, with this larger perspective, we can begin to open up to understand why Elders were listened to so respectfully, why Parents were honored so graciously, why Masculine and Feminine come together the way they do - in the roles they do - and how we, as people, as communities, as societies can fluidly move between these roles and their energies.
