God has given man the eye of investigation by which he may see and recognize truth. He has endowed man with ears that he may hear the message of reality and conferred upon him the gift of reason by which he may discover things for himself. This is his endowment and equipment for the investigation of reality. Man is not intended to see through the eyes of another, hear through another’s ears nor comprehend with another’s brain. Each human creature has individual endowment, power and responsibility in the creative plan of God. Therefore depend upon your own reason and judgment and adhere to the outcome of your own investigation; otherwise you will be utterly submerged in the sea of ignorance and deprived of all the bounties of God. Turn to God, supplicate humbly at His threshold, seeking assistance and confirmation, that God may rend asunder the veils that obscure your vision. Then will your eyes be filled with illumination, face to face you will behold the reality of God and your heart become completely purified from the dross of ignorance, reflecting the glories and bounties of the Kingdom.
