Does Buddhism teach the existence of a supreme being or God?
Buddhism has a completely different view of life than monotheistic forms of religion. Buddhism teaches the eternity of life, spanning the three existences of past, present, and future. It teaches that all beings, both sentient and insentient, go through an eternal cycle of birth and death, and appear according to internal causes (karma) and external causes (conditions in the environment).
Since each being comes into existence based on causes made in the past, Buddhism does not teach a doctrine of creation or the existence of a supreme being. The practitioner of true Buddhism realizes that one’s present existence and future destiny is completely dependent on causes made in the past and present. The practice of Nichiren Shoshu enables one to create the highest cause, through chanting Nam-Myoho-Renge-Kyo to the Gohonzon and teaching the practice to others. Thus, through chanting Nam-MyohoRenge-Kyo, one can eradicate negative karma from past causes and establish a happy life now and in the future.
