Most people have heard the story of Adam and Eve and their affair with a snake and a tree in the Garden of Eden. Few realize that it describes the essence of the struggle of every human being. Here is a brief summary, according to how it is told in the Zohar and explained by the Kabbalists and Chassidic masters:
Adam and Eve began as creatures of light. Light, for the mind, implies surrender to that which is higher and beyond, verging on anomy. As opposed to darkness, which says, “I am here. I exist.” And ultimately, “All is me. There is no other.”
The primal state of the human mind is a paradise of light; a state where all that matters is to reach to the light and to allow more light to enter.
