Context: You say that you ask only for the Truth and yet you speak like a narrow and ignorant fanatic who refuses to believe in anything but the religion in which he was born. All fanaticism is false, because it is a contradiction of the very nature of God and of Truth. Truth cannot be shut up in a single book, Bible or Veda or Koran, or in a single religion. The Divine Being is eternal and universal and infinite and cannot be the sole property of the Mussulmans or of the Semitic religions only, — those that happened to be in a line from the Bible and to have Jewish or Arabian prophets for their founders. Hindus and Confucians and Taoists and all others have as much right to enter into relation with God and find the Truth in their own way. All religions have some truth in them, but none has the whole truth; all are created in time and finally decline and perish. Mahomed himself never pretended that the Koran was the last message of God and there would be no other. God and Truth outlast these religions and manifest themselves anew in whatever way or form the Divine Wisdom chooses. You cannot shut up God in the limitations of your own narrow brain or dictate to the Divine Power and Consciousness how or where or through whom it shall manifest; you cannot put up your puny barriers against the divine Omnipotence. These again are simple truths which are now being recognised all over the world; only the childish in mind or those who vegetate in some formula of the past deny them. You have insisted on my writing and asked for the Truth and I have answered. But if you want to be a Mussulman, no one prevents you. If the Truth I bring is too great for you to understand or to bear, you are free to go and live in a half-truth or in your own ignorance. I am not here to convert anyone; I do not preach to the world to come to me and I call no one. I am here to establish the divine life and the divine consciousness in those who of themselves feel the call to come to me and cleave to it and in no others.

“There are two kinds of truth: the truth that lights the way and the truth that warms the heart.”
"Great Thought" (19 February 1938), published in The Notebooks of Raymond Chandler (1976)
Context: There are two kinds of truth: the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art. Neither is independent of the other or more important than the other. Without art, science would be as useless as a pair of high forceps in the hands of a plumber. Without science, art would become a crude mess of folklore and emotional quackery. The truth of art keeps science from becoming inhuman, and the truth of science keeps art from becoming ridiculous.
