And one of the most fascinating, and frankly mind-bending, places it takes us is to the head – or rather, the skull – of Arich Anpin.

Now, Arich Anpin – which means "The Long Face" or "The Vast Countenance" – is a concept in Kabbalah representing the divine patience and loving-kindness. And within the intricate symbolism surrounding Arich Anpin, we find something called Atika Kadisha, which is described as the skull. But this isn't just any skull. This is the skull of Arich Anpin.

And what's so special about it? The Idra Zuta, a section of the Zohar – a central text of Kabbalah – tells us that this skull is called ayin, which means "nothingness." Why? Because it's so close to the unknowable head of the Divine that it's utterly incomprehensible to us. It’s like staring into an infinite abyss. This part of the Divine is so beyond our understanding that it's essentially "nothingness" to our minds. It's not that it is nothing, but rather that our intellect simply can't grasp it.

The text goes on to say that the hairs and eyebrows on this skull aren't from the skull itself, but emerge from the "concealed brain." Why this distinction? Because, according to the Idra Zuta, judgements can’t hold on the skull of Atika Kadisha. They're all described as smooth and soft, representing pure mercy, without any harshness or judgment. It's all "the one light of Mercy," undifferentiated and boundless.

But there’s a caveat. The back of the head, the Idra Zuta tells us, isn't visible. Why? Because it alludes to Judgments. There’s a verse in Jeremiah (2:27) that says, "For they have turned their back (literally, their nape) to me, and not their face." The back of the head, in this context, symbolizes a turning away from the Divine, a separation that leads to judgment.

So, what does all this mean? Is it just esoteric mumbo-jumbo? Perhaps. But maybe, just maybe, it's a reminder that there are aspects of reality, of the Divine, that will always remain beyond our grasp. And perhaps that's okay. Maybe the point isn't to fully understand everything, but to cultivate a sense of awe and wonder in the face of the unknown. To recognize that even in the "nothingness," there's a profound and immeasurable depth.

It challenges us to consider: what parts of ourselves, what parts of the world, do we turn our backs on? And how can we instead turn our faces towards the light, towards the infinite mercy that the skull of Arich Anpin represents?
