The word spirit on the other hand recognizes and identifies that innate universal sense that life ought to be fair and problem free. The term spirit identifies the transhuman propensity to feel a kind of entitlement to order, good health, meaning, knowledge and especially joy. But in the midst of our spiritualizings, soul (psyche) collides with spirit reminding us that this world does not often comply with our sense of entitlement to joy, order and happiness. The war is on, and from it comes a unique individual. This, in part, is the significance of the Chinese Yin/Yang symbol. Each side (psyche and spirit) is telling us a part of the truth about reality, but unless both are merged, as in the term psycho-spiritual, we do not have a balanced view of human existence. Human and cultural development require both factors. Forgetting one side or the other always ends in bad politics, disappointing religion and impossible relationships. As the Tao Te Ching (poem 22) says, "We live in a perfectly imperfect world."
Finally, I do suspect that our instinctive compulsion to crave joy and wholeness exists because it actually is the ultimate goal our existence--but it arrives at the end of the soul-making endeavor--and not likely while in this earth school. Move forward and through life's challenges--toward and into increasing joy.
