In the branch of Jewish mysticism known as Kabbalah, Daʻat or Da'ath (דַּעַת, in pausa: דָּעַת , knowledge) is the location (the mystical state) where all ten sefirot in the Tree of Life are united as one. In Daʻat, all sefirot exist in their perfected state of infinite sharing. The three sefirot of the left column that would receive and conceal the Divine light, instead share and reveal it. Since all sefirot radiate infinitely self-giving Divine Light, it is no longer possible to distinguish one sefira from another; thus they are one. Daʻat is not always depicted in representations of the sefirot; and could be abstractly considered an "empty slot" into which the germ of any other sefirot can be placed. Properly, the Divine Light is always shining, but not all humans can see it. The revelation or the concealment of the Divine Light shining through Daʻat does not happen only in Daʻat itself. It can appear by a human perspective also within the worldly affairs (Malkuth). The perception of the Divine Light shining can clearly occur also in Malkuth, all the times that humans become self-giving (Altruism). However, humans who remain selfish (Selfishness) cannot see it, and for them its benefits seem "hidden". Properly, Daʻat is not a sefirah, but rather is all ten sefirot united as one. Nevertheless, Daʻat is sometimes counted as a sefirah instead of Keter, from the perspective of finite creation, using Daʻat to represent the "reflection of" (the "inner dimension" of) the infinity of Keter. Thus Daʻat appears in the configuration of the sefirot along the middle axis, directly beneath Keter. It corresponds to the . Alternate countings of the sefirot produce 10 powers ("10 and not 9, 10 and not 11" - Sefer Yetzirah) by either including Keter or Daʻat. In the scheme of Moses ben Jacob Cordovero, Daʻat is omitted, while in the scheme of Isaac Luria, Keter (Will) is omitted. Cordovero describes the sefirot as one light in ten vessels. Luria follows this, but lists sefirot beginning with Chokhmah (Wisdom) to describe their outer dimensions.
