Music exists in all the degrees of nature: the still, vegetative, and animate. In the animate degree it already becomes a form of communication, a kind of language. Animals sing to communicate between them, and for people, Baal Hasulam writes, "melody is the median between the spirituals and the corporeals."
On the human degree, music bypasses the mind, penetrates directly into the heart and can cause connection and identification.
In the clip before us, we hear various melodies, including melodies of Kabbalists, melodies that reach us from spiritual levels in which the reforming light is concealed.
