Therefore the idea of understanding the spiritual ideal is to attain to that state of being, of calm and peace and joy and everlasting happiness, which neither changes nor ceases to exist. It is to realize what is said in the Bible, "Be ye perfect even as your Father in heaven." Those words do not tell us to remain imperfect as everybody on earth. No, they mean the idea of all perfection, all unity, no separation. It is the opposite of the idea that religion should keep part of humanity separate, saying, "You do not belong to our church, our mosque, our temple!" It is the opposite of loyalty to this particular sect or community, or to that particular sacred book, to this particular teaching, or to that particular truth. Is not the source of all truth hidden in every man's heart, be he Christian, Muslim, Buddhist or Jew? Is not each part of that life which we call spiritual or divine? To be just this or that is the same as not going further than this or that. The bliss found in solitude is hidden within every human being; he has inherited it from his heavenly Father. In mystical words it is called the all-pervading light. Light is the source and origin of every human soul, of every mind.
