See the above picture of Verzy forest in the mist and read the following. ‘Eternal Feminine’ was written in Verzy Forest. It was probably different to this picture but I can’t help feeling that Teilhard experience this when he was writing ‘Eternal Feminine’:
“I am the essential Feminine.
In the beginning I was no more than a mist, rising and falling: I lay hidden beneath affinities that were as yet hardly conscious, beneath a loose and tenuous polarity.”
