According to Hindu cosmology, we're in the kali yuga, a dark period when the cow of history is balanced precariously on one leg, soon to topple. Then there are our new-age friends who believe that this December we're in for a global cage-rattling which, once the dust has settled, will usher in a great spiritual awakening. Most of this apocalyptic noise appears to be just wishful thinking on the part of people who find life too messy and uncertain for comfort, let alone for serenity and mirth.
