THE TWO GATEWAYS OF HUMAN EXISTENCE Birth and Death – The Fundamental Boundaries of Life

Among all mysteries of nature, none are more universal than birth and death. Every human being, regardless of race, nationality, religion, language, wealth, or status, enters the world through birth and departs through death. These two events serve as the opening and closing gates of human existence. This article presents the concept that birth originates from two biological causes—the female egg and the male sperm—while death arises from two major categories of causes: internal causes and external causes. Internal causes include physical and mental disorders originating within the body, whereas external causes include accidents, violence, environmental hazards, punishment, and other outside influences. This framework provides a simple yet comprehensive understanding of the beginning and ending of human life.
