Swami Jyotirmayananda is a sage, scientist, writer, Mahatma and Guru, a staunch supporter of universal yoga. In his book “The Art of Positive Thinking,” Swami Jyotirmayananda speaks of the important ability of a person with the power of thought, “the greatest power both on earth and in heaven,” to change himself as a person and thereby positively influence the reality around him and construct the events of his own life. The mind has a huge impact on the entire body and indirectly affects everything that surrounds us. Freeing the mind from negative qualities and replacing them with positive ones is called “positive thinking.”
