The Song of Life was a squale belief that the universe is one great Song which creates reality.
According to the squales, they don’t see themselves as creating the Song, but participating in it, possessing multiple layers and fundamentals with deeper meaning.
William T. Riker likened the Song of Life to Logos, from the Bible. The Gospel of Saint John. Lógos—a pretty remarkable Ancient Greek word. It means not just a word, but the concept underlying it, the act of reasoning itself. (TTN novel: Over a Torrent Sea)
