Notarikon (Hebrew: נוֹטָרִיקוֹן, romanized: Noṭāriqon) is a Talmudic method of interpreting Biblical words as acronyms.
[3]A common usage of notarikon in the practice of Kabbalah, is to form sacred names of God derived from religious or biblical verses.
AGLA, an acronym for Atah Gibor Le-olam Adonai, translated, "You, O Lord, are mighty forever," is one of the most famous examples of notarikon.
Dozens of examples are found in the Berit Menuchah, as is referenced in the following passage: And it was discovered that the Malachim were created from the wind and the fine and enlightening air, and that the name of their origin עַמַרֻמְאֵליוְהָ was derived from the verse (Psalms 104:4): "Who makest the winds thy messengers, fire and flame thy ministers" (…) And when the lights reach this Sefira, they unite and receive a name that is derived from the central letters of the following verse (Genesis 6:2): "The sons of God saw that the daughters of men were fair; and they took to wife such of them as they chose."
[4]The Sefer Gematriot of Judah ben Samuel of Regensburg is another book where many examples of notarikon for use on talismans are given from Biblical verses.
