The Meaning of the Word ''Amen''
by Rav DovBer Pinson
Amen means ‘May it be true’, it is also an acronym for ‘Keil Melech Ne’eman / Hashem is a trusty ruler.’
The word Amen comes from the word Emunah, ‘faith’, and Emes, ‘truth’. Amen is therefore a declaration of faith and truth: ‘I have faith in this; I know it is true.’
Amen is also related to the word Umnas: ‘craft’ or ‘trade’. This teaches us that generating authentic spiritual faith and conviction requires skill and labor.
Numerically the word Amen is 91 as the Hebrew word Malach / Angel. Every time we recite Amen we create “angels”; releasing healing / positive vibrations into the world.
91 also corresponds to two primary names or manifestations of Hashem. Hashem [the Yud-Hei-Vav-Hei] is numerically 26. Hashem is the Transcendent ‘Beir’ of Beingness. Ado-noi is numerically 65. Ado-noi is the manifestation of the Transcendent One within creation - 26+65=91.
By saying Amen we are drawing down Blessings from the Highest High into the lowest vessels possible.
