In plain words
Only then does the equanimity in us reach the divine form of the Ātma. We need not doubt whether this oneness is possible in this world. Because our delusions take on distortions born of the guṇas, an infatuation with manyness has spread over us. A small example of this. In the cinema, pictures appear in many ways. But all these pictures are gathered on one tape, and only because of that does this electric power, spreading over that tape, become the root cause of showing many kinds of varied pictures on it. Yet these varied pictures are only mental things, imaginings; they cannot be changes in the electric power. There is only one electric power. There is only one tape. Because that tape keeps turning as a shadow of the electric power, all the varied images delude us. In just the same way, because all the pictures called our senses gather on the tape called the mind, we, through the current called the intellect, mistake this world for a few vast pictures. Only because these senses join with the mind and follow the intellect do they take on, for us, varied pictures and different forms and names. When those same senses reach the heart through the mind, he comes to see his own principle, his own true form. But the principle of the heart in us takes on all sorts of forms, goes through manifold experiences, and keeps showing the world many kinds of difference within the individual. When we try to know the seat of the Ātma, delusion about so many kinds of forms and names does not grow; the citta clings to the divine oneness alone. Another example of this. A person takes on various names and forms in films and acts in several kinds of plays; or, on several stages, one and the same person takes on various names and forms and carries out his duty. Then, to bring out the truth of whether this person, who takes on forms and names and acts in plays on four stages, is one or four, we must make some kind of effort.
