“the human soul is part of the great cosmic stream that flows through all creatures. It is a single force, one motion, but when a person is born into a physical body, when he comes into the world as an individual being, that soul has to separate from the rest, otherwise a person would not be able to live—the soul would drown in the One, and the person would go mad in just a few instants. That is why such a soul gets sealed, that is, seals are stamped upon it that will not let it mix with that unity but will allow it to operate in the finite, bounded world of matter.”
