Da'ath:  knowledge
"The Abyss"
The Non-Sefirotic "Sephira"
[On the Sephirothic Tree, Just  beneath - at the gate of -Binah (Understanding) and Chokhmah (Wisdom)]

Interestingly, this is the same word -da'ath - used for "Knowledge" in the following scripture:
Genesis 2:17:  "But of the tree of the knowledge ["da'ath"] of good and evil, thou shalt not *eat of it:  for in the day that thou eatest thereof thou shalt surely die."
*eat:  h398. 'akal; to eat (lit. or fig.):--burn up, consume, devour (-er), dine, feed with
h399. 'akal; corresp. to H398:--accuse, devour, eat


"Da'ath is "the secret sphere of Knowledge on the cosmic tree."

- Perle Epstein, Kabbalah - The Way of the Jewish Mystic

da'ath, 'knowledge'. This refers to the omniscience or universal consciousness of God which, properly speaking, is not a Sefirah, but the cognitive presence of the One in each of them."
- Leo Schaya, The Universal Meaning of the Kabbalah

"The word for "knowledge", da'ath, has a technical meaning.  When the Bible was translated into Greek, the word da'ath was translated as "gnosis". Da'ath has a very peculiar status in Kabbalah, being a kind of non-existent, a nothingness. In modem Hermetic Kabbalah it is sometimes represented as "a hole or gate into an abyss of consciousness". Crowley's experiments with "the Call of the Thirty Aethyrs" led him into this abyss."

- Colin Low

"And by Da'ath, the rooms [or spiritual 'receptivities'] are filled with all precious and pleasant [Sephirothic] riches."

- Proverbs 24:5
"When Malkuth ['Kingdom'] 'fell' out of the Garden of Eden it left behind a 'hole' in the fabric of the Tree, and this 'hole', located in the centre of the Abyss, is called Da'ath, or Knowledge. Da'ath is not a sephira; it is a hole."
- Colin Low, "Notes on the Kabbalah"
Da'ath: the mysterious knowledge, the great abyss

"Unlike the sephirah which represent states of mind rather than static placements, and the paths of lessons learned to move from one sephirah or concept to another, Da'ath is not represented upon the Qabalah tree. It is placed below the three supernal sephirah - Kether (the crown), Binah (+) and Chokmah (-). The polarities of positive and negative alternate up and down the tree and cause the energies to circulate as the universal input is pulled downward through the tree supernal sephirah to Da'ath. In this void between the higher and the lower the hither to formless energy of the universe takes on material shape by crystallization. Here is the highest point of the human mind: the home of the brainstorm or creative energy that is brought into manifestation on the earthly plain. As the sand passes through the narrow center of the hour glass, so does knowledge incoming from the universe pass into our consciousness in the machinery of Da'ath. Here is the ultimate home of intuitive knowledge from which all concepts stem.
"When working with the tree either to call down the greater knowledge of the superhuman universe and its infinite organization, or to bring our self up the tree from the lower sephirah for spiritual upliftment and higher perspective, all energy must pass through Da'ath on its way into matter or disintegration into the hypertext of the universe. Thus the term mysterious knowledge is given to Da'ath  where wisdom (Chokmah) is combined with understanding (Binah) and melded to the material level through the influence of Tipheret (sixth sephirah: balanced harmony) which pervades one's soul with the concealed light of illumination of consciousness."

"DA'ATH - Knowledge - is not a Sephira. It is not on the Tree of Life: that is, there is in reality no such thing.  Da'ath is the crown of the Ruach, the Intellect; and its place is in the Abyss. That is, it breaks into pieces immediately as it is examined."

 - Aleister Crowley, Little Essays Toward Truth


"Da'ath has a dual aspect; on one hand it is our knowledge of the world of appearance, the body of facts which constitute our beliefs and prop up the illusion of identity and ego and separateness. On the other hand it is revelation, objective knowledge, what is often referred to as "amosis". The transition between the knowledge of the world of appearance and revelation entails the experience of the abyss, the abolition of the sense of ego, the negation of identity. From within the abyss any identity is possible. It is Chaos, unformed. It contains, as it were, the seeds of identity. It is from this point that an infinity of gates open, each one a gateway to a mode of being [the Many Faces]. These are referred to as the 'Gates of Knowledge'."

Hebrews 5:15 (KJV):  "But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to *discern - separate thoroughly, withdraw from, discriminate - good and evil."
