Apocalyptic (literature)

For a modern mind, the word "apocalypse" means a great world disaster. But in fact, it is the transcription of αποκαλυψιζ a Greek term which simply means "laying bare," "unveiling." Uncommonly used in non-religious Greek, it appears rather often in the biblical translation of the Septuagint, where it refers to a "laying bare" in the material sense, but above all, in the figurative sense, to the "revelation" of human or divine secrets.

To Sujata
with whom, step by step, we went through those terrible ordeals, supported by our sole love for Mother
and our desperate will to continue Their Work until the end
