Tantalus was admitted into fellowship with the Gods, i.e., he represents an ego which has made intimate contact with the transpersonal psyche and has become privy to the secrets beyond the ‘epistemological curtain.’
Edinger recasts Tantalus’s punishment as the inevitable burden borne by an ego that has crossed the threshold into transpersonal divine knowledge, implicating him in the ongoing process of divine transformation.
