Situated in the Abyss, Da'ath (דעת) is knowledge without understanding. Also called The False Head, it can look like Kether coming up the Tree, but don't be fooled: it is in the Abyss, and is also the gateway to the Qliphoth (קליפות), the spheres of negative influence that are the Qabalah's reverse side.

Many Qabalists say that "Where Da'ath is, Kether is Not." Da'ath, whose name means "knowledge", is the child of the Supernals whose home is the Abyss. It summarizes, but cannot take the place of, the Supernals. They themselves are "knowledge": Kether is knowledge, Chokmah the knower, and Binah that which is known. Da'ath then is the imperfect reflection of that supreme knowledge — but perfect enough to delude the seeker into thinking that it is the supreme knowledge. Beware: this is not the top of the Tree!

Sefer Yetzirah tells us that Da'ath does not exist, saying there are "Ten Sephiroth of Nothingness; ten and not nine, ten and not eleven".
