It demands a lot of reflection every day to understand life. Life consists of perception and action. Most people, however, only try to control their actions and do not realize the importance of perception for their lives. Every individual's actions at any given moment in time are determined by the way he or she perceives the world. This book is meant for all those who really want to understand life.
