Many believe the answer is Hebrew.

It's a pretty powerful idea, right? That the very letters we use to write down these words are echoes of something ancient, something divine. A primordial tongue.

Tree of Souls explores this idea, particularly the notion that Hebrew isn’t just a language we use here on Earth. It's the language of the heavens, the language of the angels themselves.

This wasn't just some fringe belief, either. It was a central assumption in rabbinic literature. We're talking about a bedrock principle, the idea that Hebrew is a lashon ha-kodesh, a sacred tongue.

Think about that for a second. The very sounds and shapes of the Hebrew alphabet, the alef-bet, are thought to resonate with a deeper spiritual reality. It’s a language spoken not only here in our world, but also in the celestial realms.

Even the Karaites, a Jewish movement known for accepting the Bible while rejecting the Talmud, held this belief. This is evidenced in Kitab al-riyad w'al-Hada'ik. This shows us just how widespread and deeply ingrained this idea was within Jewish thought.

So, next time you see a Hebrew letter, or hear the words of the Torah chanted, remember that you're not just encountering a language. You're potentially tapping into something far older, something closer to the very source of creation. A language that connects us not only to each other, but perhaps, to the divine. Is it any wonder that Jewish mystics have spent centuries contemplating the power and secrets held within these ancient letters?
