Most people who are not Buddhists often wonder what Buddhism is. This book generally describes how Buddhism has appeared and what Buddhism is. Unlike many other religions, which worship deities in the heavens and often pray to these deities for blessings in life and the promise of a heavenly afterlife, Buddhism focuses on enhancing human morality in the present life. It helps individuals achieve an obvious and pure inner state of mind, known as Enlightenment. An enlightened person can understand everything in the universe. Therefore, Buddhism also serves as a beautiful complement to other religions.
