The line of esoteric transmission of European religions has been broken, however, the three main eastern traditions have preserved many esoteric aspects of the western branch. Buddhism, Jainism and Hinduism can help us reestablish this chain of transmission through initiations and esoteric knowledge.
This method of transmission has already been historically adopted by the Romans who learned about augury and esotericism from the Etruscans. Religious teachers from these traditions are more competent in rebuilding our esoteric heritage than any academic reconstructionist.
