I wonder if these paragraphs from a paper I wrote on the subject of "speaking in tongues" would be relevant here:
Language and the Unconscious
...When on Pentecost the "tongues" of fire appeared over the heads of those gathered in the upper room, the result was that they began to speak in unknown "tongues" "as the Spirit gave them utterance." Here the word "tongue" is used in three ways: (1) as the licking shape of fire; (2) as a member of the body which facilitates speech; and (3) as a synonym for diverse languages. To say they spoke "as the spirit gave them utterance" implies that although the mechanism of speech was theirs, the words were not, at least not in the ordinary sense. Metaphorically understood, the description could be taken to mean that their speech was "inspired" or "anointed." In light of individuation symbolism, a possible interpretation could be that the disciples spoke with the voice of the transcendent Self, or from Aurobindo’s "supramental" level of higher consciousness.
