AGLA is a notariqon (kabbalistic acronym) of the phrase "Ateh Gibor Le-olam Adonai,"The Lord is mighty forever."

AGLA is used in its short form in a number of magical circle making forumulas. The Golden Dawn used it as the "God Name" of the North quarter in the LBRP, representing Earth, and in the GRP to represent the passive elements of water and Earth.
