" Certainly, all esoterism appears to be tinged with heresy from the point of view of the corresponding exoterism, but this obviously does not disqualify it if it is intrinsically orthodox, and thus in conformity with truth as such and with the traditional symbolism to which it pertains; it is true that the most authentic esoterism can incidentally depart from this framework and refer to foreign symbolisms, but it cannot be syncretistic in its very substance. "
