The transfiguration of Jesus is a long alchemical and kabbalistic process that occurs within those who follow the path of initiation. First, one must generate Moses and transfigure him. Thereafter, through the exodus, Elijah incarnates and is taken alive into heaven. All of these generations and transformations happen within the spirit, soul and body of the alchemist. Yet, these mysteries are unknown to the uneducated, who have only been fed "milk" for babies:

"For every one that uses milk is unskilful in the word of righteousness: for he is a babe. But strong meat belongs to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil." - Hebrews 5: 11-14

"And after six days Jesus took Peter, James, and John his brother, and led them up on a high mountain by themselves; and he was transfigured before them: and his face did shine as the sun, and his raiment was white as the light. And, behold, there appeared unto them Moses and Elijah talking with him." - Matthew 17: 1-3
