Most world religions emphasize the principle of Oneness. It is discussed by many great masters, and is ultimately the goal of all existence. Our purpose is not to just feel this Oneness occasionally, but to live in a state of constant Oneness with all people, all animals, and all things.
Just like fingers are to a hand, that is our relationship to God. We are all extensions of the great Brahman. Our lives are intertwined with every sentient being on the entire planet. When one person suffers, we all suffer. When one person feels joy and compassion, it also changes our world. All of the consciousness of the planet flows into and from the great consciousness of God. There is nothing in the universe but God.
