Since you mentioned the Kali Yuga in TLTE, a concept closely related to your "age of devilry", I watched this presentation on the Yugas:
Interestingly the scholar maintains that some people have the dates of the yugas wrong and that the correct timing shows that the last kali yuga finished in 500 AD*. We are currently in an ascending phase of a new "bronze age" Dwapar yuga. In contrast to yourself he takes the technological and scientific growth of the past thousand years to be a positive sign in alignment with the increasing mental virtue associated with coming out of the kali yuga.
*correction: 500 AD is the lowest point of the last kali yuga and it finished in 1700 AD.
It is interesting, thanks for sharing. I myself subscribe to the idea that natural man cannot help but descend into a downward cycle, and that his technological and scientific hubris are a sign of that downward spiral, not a sign of ascent and mental virtue. This video could well be the result of the influence of Western Civilization's Promethean Optimism at work, which leaves no other culture untouched these days.
We (Mankind in the whole world) today are embedded within a Civilization, Spengler's ''Faustian''(Western) Civilization that believes that we are indeed on an ascent, which they hope to be permanent, to break any possible cycle and expand out into the cosmos, ever expanding and ever evolving higher and higher. I suspect however at it's core, there is no longer such a belief in the heart among the Western Elites, but it lumbers on pushing them onwards none the less.
Believe me, the Pagan and Hindu/Vedic/Buddhistic Cycles are more pessimistic in a sense than I ever could be, because being a Christian (Spengler's ''Magian'', along with the other Monotheists) these ages wind up to an End, the Second Coming, where thereafter there shall be no end of the direct Reign of God, where the Kingdom of God lives in all hearts and literally exists in this world forever.
What this video does show inadvertently is that man does not have a universal culture (although the Faustian aspires to it) but is possessed presently of several cultures with competing worldviews. I happen to believe that the worldview i've had all my life happens to be the correct one, and that my position within the Western culture (like that of all true Christians) affords me a certain objective vantage point from which to analyze Western decline dispassionately.
If we are to discuss these matters, I must remind you that in previous conversations with ''Pagans'' (not saying you are of that sort or not) that I believe very literally in the beings they claim to worship, but do not of course worship them or ascribe to their deceits, for deceivers they are. What I have found however, is that most ''pagans'' I have come across do not believe in the existence of the beings they follow, their worldview is more a kind of ''Atheism in drag'' if you will, Nietzsche plus pagan rituals or whatever. I however take paganism seriously at least, just as my Christian forebears would in the early centuries of the Faith.
I would also remind you that I am also quite serious about the ideas expressed at the beginning of this thread, that cosmologically I live in a very different universe than most in the modern age, and therefore do not believe in the standard assumptions of the modern cult of ''science'', either.
But man is a fickle and disreputable creature and perhaps, like a chess-player, is interested in the process of attaining his goal rather than the goal itself.
