We're diving into the mystery of the name AV (אב), which has a numerical value of 72. But it's not just the simple numerical value that's important; it's how that number 72 manifests in different expansions and forms of the name. The Kalach Pitchei Chokhmah, a Kabbalistic text, unlocks this secret for us.

This isn't some new-fangled idea. As the Kalach Pitchei Chokhmah tells us, these concepts are already clear in the teachings of Rabbi Shimon bar Yochai, the sage traditionally associated with the Zohar, and the holy ARI, Rabbi Isaac Luria, the towering figure of 16th-century Kabbalah. Each of the four names – AV, SaG, MaH, and BaN – contains 72, but in a unique way. Think of it as different facets of the same divine diamond. First, AV (אב) itself. In this case, the numerical value of the letters Aleph (א = 1) and Bet (ב = 2) simply add up to 3. When we fully write out the letters of the name we arrive at 72, the simple sum of its constituent letters.

Now, for SaG (סג), which equals 63. Here, we reach 72 by adding 10 – one for each of the ten letters when the name is spelled out in full. 63 + 10 = 73. We then subtract 1 which is the kolel, signifying the overall unity of the name. The kolel is a fascinating concept in itself, representing the idea that the whole is greater than the sum of its parts.

Next, we have MaH (מה), equaling 45. To get to 72, we add the numerical value of the simple name of God (יהוה), the Tetragrammaton, which is 26 (Yud=10, Heh=5, Vav=6, Heh=5). So, 45 + 26 = 71. And again, adding one extra unit for the kolel brings the total to 72.

Finally, BaN (בן), which is 52. This one's perhaps the most intriguing. We reach 72 by reckoning the fourfold form (ribu’a) of the Name. What does that mean? It's like a progressive expansion: Yud (10) + Yud-Heh (15) + Yud-Heh-Vav (21) + Yud-Heh-Vav-Heh (26) = 72. We're essentially building the name step-by-step, adding a letter each time and summing the values.

What’s the significance of all this numerological gymnastics? It’s not just about numbers. It’s about understanding the different ways in which the Divine manifests itself in the world. Each name, each expansion, represents a different aspect of God’s attributes and energies. By understanding these relationships, we can gain a deeper insight into the nature of reality itself.

So, the next time you encounter these names, remember that there's a whole universe of meaning hidden within them. It's a reminder that even the smallest details can contain profound secrets, waiting to be unlocked. What other hidden meanings might we find, if we only know where to look?
