One day, during one of the breathing exercises, I felt myself carried into space, very far, very high, and suddenly I heard that the whole universe was singing: the mountains, the trees, the seas, the whole earth, and also the suns, the stars, everything sang.
All of Creation was just music. No human music can compare to what I heard. I said “I heard”, but in fact it is only a manner of speaking: this music could not be heard with the physical ears, but with the soul and spirit.
This symphony of the whole universe, which poets or philosophers like Pythagorus and Plato have called the « harmony of the spheres » or « the music of the spheres ». Everything that exists emits sounds…The music of the spheres is this synthesis of all the languages which Creation uses in order to manifest.
