Ichinen Sanzen, the Three Thousand Worlds Contained in One Thought, is the theoretical cornertone of Nichiren Buddhism. It is a universal vision of life as rich, dynamic, and meaningful. Ichinen Sanzen reveals thal all life contains all Ten Worlds, including Buddhahood, and that these worlds operate according to the causes and conditions that we all set in motion. In a praclical sense, this theory means that we are able to make the cause that will allow the world of Buddhahood to emerge in our lives when we chant Namu Myoho Renge Kyo.
