An Inner Meaning of 666

I’ve been busy this week between Pesach and a community program for kids that I’m helping to run, but there will be numerous new articles coming soon. In the meantime, I wanted to share a quick revelation.
The Hebrew vowel called kametz hagadol (a T-shape one found under certain letters  and comprised of a horizontal line with a dot centered underneath it) is equivalent to the highest sefira (dimension), that of Keter (crown).  This little bit of information is important for the article I’m preparing on the “4 Passover questions;” nevertheless, when the kametz hagadol is combined with each of the letters of the Tetragrammaton (YHVH), the gematria value of the Name of G-d takes on a different aspect.
YHVH is typically of numerical value 26, and each of the 4 dots of the 4 kametz hagadol beneath the letters is of value 10, making 40 more, or 26 + 40 = 66
The secret of the horizontal line of the kametz hagadol is that it is a vav (V) representing Zeir Anpin and typically the numerical value 6, but the four vavs together create a mem sofit (ם ) (final letter mem), of numerical value 600
Thus the YHVH (at the level of Keter) with the kametz hagadol beneath each of its letters is numerically equivalent to 26 + 40 +600 = 666

So when we speak of the role of 666 as in the 66.6 jubilee years from the Exodus in 2448 to 5778 , or as in Rav Yehuda HaLevi Ashlag’s calculation of the year 5778 for the arrival of Moshiach, we can better understand to what we’re really connecting.
