"I feel -- not Doubt of Masters who hear any heartbeat in the right direction, but -- a terrible Despair of these people. Oh, my God! The age is black as hell, hard as iron. It is iron, it is Kali Yuga. Kali is always painted black. Yet Kali Yuga by its very nature, and terrible, swift momentum, permits one to do more with his energies in a shorter time than in any other Yuga. But heavens, what a combat! Demons from all the spheres; waving clouds of smoky Karma; dreadful shapes; stupefying exhalations from every side. Exposed at each turn to new dangers. (Vol. I, Letter 7)"
