The Aramaic Alaha, the common name for the Divine in the language that Jesus spoke, is in turn related to the Arabic Allah: ‘The God’, and the Hebrew: Eloah [Elohim, Elohai]. It was originally a loose reference to a regional deity and in-time appropriated into emerging Islam.
The principle prayer of Islam, the Shahadah reads:
‘La Ilaha il al-Lah’: ‘There is no God if it be not the God’.
The second part, a possible later addition but the Islamic Doctors are of mixed view on this, reads: ‘And Mohammed is His Messenger’ [the entire prayer can be seen scripted on numerous national flags].
‘La Ilaha il al-lah’, is an informed rendering of insight as Self-Eating Expression meant for the trained ear and in the language of the day.
But in the wrong hands this summary warning against man-made gods itself becomes a man-made god. You destroy the idol while idolizing the Book. If you read it off the Koran literally and are clueless of looping language, the Shahadah becomes: ‘There is no God but MY God’.
In High-Sufism the final stage of practice is termed Fana al-Fana, the ‘Annihilation of Annihilation itself’. A defiantly powerful Self-Eating Expression, naturally, necessarily.
[Sufism, like the mystical Jewish Kabbalah, and the parallel Hindu Bhakthi Tradition, has largely avoided confronting the entirety of this algorithm, avoided the infinite regress and settled instead to a praise of God, Goodwill and Universal Love.]
