Indian Spirituality and Life (1919) 
Context: Indian religion never considered intellectual or theological conceptions about the supreme Truth to be the one thing of central importance. To pursue that Truth under whatever conception or whatever form, to attain to it by inner experience, to live in it in consciousness, this it held to be the sole thing needful. One school or sect might consider the real self of man to be indivisibly one with the universal Self or the supreme Spirit. Another might regard man as one with the Divine in essence but different from him in Nature. A third might hold God, Nature and the individual soul in man to be three eternally different powers of being. But for all the truth of Self held with equal force; for even to the Indian dualist God is the supreme self and reality in whom and by whom Nature and man live, move and have their being and, if you eliminate God from his view of things, Nature and man would lose for him all their meaning and importance. The Spirit, universal Nature (whether called Maya, Prakriti or Shakti) and the soul in living beings, Jiva, are the three truths which are universally admitted by all the many religious sects and conflicting religious philosophies of India. Universal also is the admission that the discovery of the inner spiritual self in man, the divine soul in him, and some kind of living and uniting contact or absolute unity of the soul in man with God or supreme Self or eternal Brahman is the condition of spiritual perfection. It is open to us to conceive and have experience of the Divine as an impersonal Absolute and Infinite or to approach and know and feel Him as a transcendent and universal sempiternal Person: but whatever be our way of reaching him, the one important truth of spiritual experience is that he is in the heart and centre of all existence and all existence is in him and to find him is the great self-finding.
                                    
“It is for philosophy of religion to find out whether the convictions of the religious seers fit in with the tested laws and principles of the universe.”

General sources 
Context: Science doesn't purvey absolute truth. Science is a mechanism. It's a way of trying to improve your knowledge of nature. It's a system for testing your thoughts against the universe and seeing whether they match. And this works, not just for the ordinary aspects of science, but for all of life. I should think people would want to know that what they know is truly what the universe is like, or at least as close as they can get to it.
