To act and act wisely when the time for action comes, to wait and wait patiently when it is time for repose, put man in accord with the rising and falling tides (of affairs). So that with nature and law at his back, and truth and beneficence as his beacon light, he may accomplish wonders. Ignorance of this law results in periods of unreasoning enthusiasm on the one hand, and depression on the other. Man thus becomes the victim of the tides when he should be their Master.
H. P. Blavatsky
