Now back to post 114 which I asked about and Q said he thought came from Kabbalah.
YHVH: The Tetragrammaton
The most powerful and important Name of God, which appears in the Torah, is
YHVH, also referred to as the
Tetragrammaton and the
Ineffable Name. Its pronunciation has been lost; it was formerly uttered only by the High Priest on Yom Kippur (The Day of Atonement). Many scholars have speculated on its pronunciation, producing names like "Jehova" and "Yaweh".
Jews do not even attempt to pronounce this name; rather, a lesser Name is substituted, most commonly "Adonai" in prayer, though some Jews may use "casual" and respectful substitutes such as "Adoshem" or "Ha-Shem" ("The Name") outside of prayer.
I did not find anything about a 72 letter name but this one.
The Holy and Awesome 72-Part Name
Known as The 72-Part Name is made out of 72 triads of letters, and is one of the most powerful Names a Kabbalist might use. It is derived from Exodus 14:19-21, each line of which has 72 letters. To create the first triad, you put together (from the Hebrew) the first letter of 14:19, the last letter of 14:20, and the first letter of 14:21. To create the second, the second letter of 14:19, second to last of 14:20, and the second of 14:21. Continue until all the letters are used up.
Legend has is that this Name was revealed to Moses at the Burning Bush, and is what he used to part the Red Sea. Some speculate that this is the Name the High Priest would utter during the High Holidays.
This is a sort of "blanket" Name used to vanquish demons, put out fires, heal, kill, gain the favor of a king, etc. However, if it is said in a state of impurity or uncleanliness the utterer will be struck dead! Probably due to its complexity and inherent danger, this Name was divided up into parts (that is, shorter series of triads), and these parts could in turn be used or specific purposes. The exact uses and how exactly the Name was to be divided up varied somewhat among Kabbalists. I have found a small number of examples, but consider the matter a bit too complex and grey to spell everything out here.
So my question still stands where did the part of ending the world come in.
