The Dark Age and Buddhism’s future

"Based on new evidence, it seems that the so-called “Dark Age” may have been a Golden Age—for non-monastic Vajrayana. What was destroyed in 842 was monastic Buddhism.1 For ngakpas, the Dark Age was splendid: one could practice Tantra free from the narrow-minded moralizing of monastic busybodies and the political imperatives of feudal warlords."
