The perennial nature of evergreens like this rhododendron speaks to the perseverance of plants to continue even through the persistent cold and blowing snow of the winter season. During the winter-time they set their roots more deeply. The energy of the sun persists in this deep rooting.
People can be like that. We walk upright on the earth, our heads to the sun and our feet to the ground, rooting our souls (soul=sol, another name for the sun) into our life on earth. Our life on earth is the horizontal plane our arms make when we expand them to take another person into a hug or in an act of prayer, like the trees reaching out their branches, also to the sun.
All of us participate in life. During the day time we go about the business of living – plants, animals, people. At night something different happens. When the action of life pauses with the night time, the energies of the diverse kinds of trees in the forest blends. This blending is a kind of oneness, like the mystics talk about when they claim, “All is One!” We can experience this merging in our awareness of the life forces surrounding us.
