precious metal is the mother of water

Autumn is Metal:
"If you're really listening, if you're awake to the poignant beauty of the world, your heart breaks regularly. In fact, your heart is made to break; its purpose is to burst open again and again so that it can hold ever-more wonders."

Andrew Harvey, The Return of the Mother

And Winter is Water:
"This mind of endless effortless movement is what we strive to emulate in Aikido. Joining with, absorbing, surrounding, and protecting all that we encounter, regardless of the perceived adversity. Through our practice we come to embody the emotional understanding that we are very much the same as all of life. Each of us engaged in the inevitable journey back to the center of the universe, to die and be born again."

Senta Yamada sensei
founder of Kikusui Kai Aikido

Springtime is Wood:
"Too often we focus exclusively on the objectives, reacting to the failure of its immediacy with frustration and impatience. One wonders if the apple seed, too, experiences this frustration and sense of dashed hopes as it grows into a wooden stick that in no way resembles the apple it was promised it would become."

Rabbi Gerson Winkler

Summer is Fire:
"I am the joy of the desiring flesh
The days of my living
are summer days
The nights of my glory
outshine the blazing wavecaps of the heavens
at their floodtide
Mine is the confident hand shaping this world."

Kenneth Patchen

And this is Earth, sometimes called the season in-between the seasons, sometimes called Indian Summer, sometimes called the center and axis of the wheel as it turns:

"I can never be what I ought to be until you are what you ought to be. This is the interrelated structure of reality."

Dr. Martin Luther King Jr.
