Our idea of ​​man differs according to our feelings and beliefs. The material person and the spiritual person accept the same definition that is given to a crystal of chloride, but they do not agree with each other in defining a living being. The physiologist who researches the body''s mechanical processes, and the physiologist who researches the doctrine of life itself, cannot look at the human body from one angle. The human race has made a tremendous effort to know itself, but although we have a treasure trove of observations accumulated by scientists, philosophers, poets, and great spiritual scholars of all times, we have been able to understand only certain aspects of ourselves. We do not understand the human being as a whole. We know him. However, it is made up of different parts, and even these parts were created by our means. Each one of us is made up of a procession of ghosts, in the middle of which an unknown truth marches.In fact, our ignorance is complete. Most of the questions that those who study the human race ask themselves remain unanswered: What is the nature of our psychological and physiological makeup? What is the relationship between feeling and the brain that is still a mystery? To what extent does will affect the body? How is the mind affected by the state of the organs?
