Nowadays life never gives man a moment to be quiet that he might have time to ponder upon the true cause of his constant unhappiness. Also it keeps him in an illusion, always looking outward, and he can never find the cause outside himself. It is as if he were looking for the moon on earth, though the moon is in the sky. But then you may ask, "What has man lost?" And the answer is God Himself. That perfect intelligence that is in every being, that intelligence that the Vedanta calls "Light." The verses of Qur'an say, "God is light, Nur," which means that the light of God is immanent in the world of names and forms, in all that exists in this world of variety. In this world of variety different forms of activity are producing different results. And man in this life of illusion has yet the same intelligence, which he can realize in its perfection in that state of consciousness where he can be aware of his own perfection.
