"What are the evidences of conscious intelligence beyond the material universe?”

... "Material virtues have attained great development, but ideal virtues have been left far behind. If you should ask a thousand persons, “What are the proofs of the reality of Divinity?” perhaps not one would be able to answer. If you should ask further, “What proofs have you regarding the essence of God?” “How do you explain inspiration and revelation?” “What are the evidences of conscious intelligence beyond the material universe?” “Can you suggest a plan and method for the betterment of human moralities?” “Can you clearly define and differentiate the world of nature and the world of Divinity?”—you would receive very little real knowledge and enlightenment upon these questions. This is due to the fact that development of the ideal virtues has been neglected. People speak of Divinity, but the ideas and beliefs they have of Divinity are, in reality, superstition. Divinity is the effulgence of the Sun of Reality, the manifestation of spiritual virtues and ideal powers. The intellectual proofs of Divinity are based upon observation and evidence which constitute decisive argument, logically proving the reality of Divinity, the effulgence of mercy, the certainty of inspiration and immortality of the spirit. This is, in reality, the science of Divinity. Divinity is not what is set forth in dogmas and sermons of the church. Ordinarily when the word Divinity is mentioned, it is associated in the minds of the hearers with certain formulas and doctrines, whereas it essentially means the wisdom and knowledge of God, the effulgence of the Sun of Truth, the revelation of reality and divine philosophy." ...
