Context: There are periods in the history of the world when the unseen Power that guides its destinies seems to be filled with a consuming passion for change and a strong impatience of the old. The Great Mother, the Adya Shakti, has resolved to take the nations into Her hand and shape them anew. These are periods of rapid destruction and energetic creation, filled with the sound of cannon and the trampling of armies, the crash of great downfalls, and the turmoil of swift and violent revolutions; the world is thrown into the smelting pot and comes out in a new shape and with new features. They are periods when the wisdom of the wise is confounded and the prudence of the prudent turned into a laughing-stock....

“You seem to have learned quite a lot over the years.”
“It is the privilege of old people to seem to know everything. But it’s an act and a mask, like every other act and mask. Between ourselves, we old ones wink at each other and smile, saying, How do you like my mask, my act, my certainty? Isn’t life a play? Don’t I play it well?”
They both laughed quietly.

Context: Wisdom is not communicable. The wisdom which a wise man tries to communicate always sounds foolish... Knowledge can be communicated, but not wisdom. One can find it, live it, do wonders through it, but one cannot communicate and teach it.
