"The ancients believed the World to be composed of 4 basic elements – Fire, Water, Air and Earth. These were considered the critical energy forces that sustained life. All of these elements are integral parts of matter or the physical universe, and the human body is a physical creation existing in the material realm. Therefore, the human beings were seen to be made of and governed by the four elements. Maintaining a balance between these elements was advocated to ensure physical as well as psychological well-being".
