"Yesterday a conversation about divinity and faith suggested to me a great, a stupendous idea to the realization of which I feel capable of dedicating my whole life. This is the idea—the founding of a new religion corresponding to the development of mankind: the religion of Christ, but purged of all dogma and mystery, a practical religion, not promising future bliss but realizing bliss on earth."
