The name Judas (Greek) is a translation from the Hebrew name Judah, the most exalted tribe of Israel. In Hebrew, Judah is יהודה, a very significant name that joins the most holy name of God (יהוה) with the letter ד Daleth, which represents a doorway and is the first letter of the word Daath (knowledge), indicating the secret teachings.
The name Judas is most known in relation to two disciples of Jesus, particularly Judas Iscariot, who led the Rabbis to Jesus and began the process of his torture and crucifixion, a role that has since associated the name Judas with betrayal.
"Judas Iscariot is not as many think, a man who betrayed his Master. No! Judas Iscariot performed a script taught by his Master, and that is all! Jesus of Nazareth himself prepared him, and Judas learned this script by memory, thus, consciously, he played his role in public. The doctrine of Judas signifies the elimination of all our psychological aggregates: death to the ego. This is why Judas “hung himself,” in order to indicate that the ego must be reduced to ashes. Judas followed a script, and nothing else. He prepared himself conscientiously in order to not contradict at all the sacred scriptures. Just as any actor performs his role, Judas rehearsed it many times before performing it in public, and nothing more. Judas is and continues to be the most exalted disciple of Jesus of Nazareth. Judas achieved Christification." - Samael Aun Weor, Kabbalah of the Mayan Mysteries (1977)
