In plain words
Three moons
In the moving water of a river a moving moon is seen! At the same time, in the still water of a pond the moon is seen as though it stood fixed; and in the sky there is one moon, the witness of all, without attributes. The jīva who moves about in the world doing his karmas, and the yogī who with a steady intellect has curbed the mind and the senses in dhyāna: these two are only reflections of that Witness of the world; according to the nature of the vessel they seem to move or to stand still, that is all. The Ātma, the witness of all, is itself without attributes and without form.
Of the moving reflection Jesus Christ said, “I am the messenger of God” (I am the bearer of the message, come for God's work); recognising the reflection of the yogī within Himself, the one that had become steady, He said, “I am the Son of God” (I am the Son of God); naming the formless principle that stands as witness in the sky, He declared, “I and My Father are one” (I and My Father, the two of us, are one). If people recognise the truth that all are only reflections of Him whose very form is the Ātma, and accept the brotherhood of man and the fatherhood of God, that itself becomes the foundation of the welfare of the world. That itself is the essence of all religions, the aim of all paths, the goal of all beings. Not recognising this, people in every country fall into unrest, wrongdoing and injustice, take up dreadful propaganda, and drive their lives along the road to ruin.
