The real meanings hidden in the symbols of Cain, Abel, and Seth and the mark or seal of Revelation. Lecture quote:

"Daath [דעת] is Hebrew and means knowledge.  It is spelled with three letters:  Daleth [ד], Ayin [ע], and Tav / Tau [ת].

The Tree of Knowledge is one of those symbolic trees described in the myth of Adam and Eve. In order for us to grasp the meaning of Daath, we have to first grasp that Adam and Eve are a myth—not a myth in the sense that it is not true or not real, but a myth in the sense that it is a mystery.  Adam and Eve is a mystery—a story that contains and hides the truth.

The mystery of Daath relates to the entirety of what we are as Being."
