It's monkeys and typewriters. The odds of nobody getting enlightened - when so many are seeking truth - are very slim.
The first hint we should have that meditation is not a passive withdrawal into a mental shell is this: Meditating is actually really hard! Things that are passive tend to be easy, right? Watching Project Runway for half an hour is a piece of cake. Watching your mind for half an hour, not so much. The truth is that mindfulness — paying direct attention to what our thoughts do in the present moment — is not at all peaceful, at least not in the “easy” sense of the word. Anyone who has tried it on a regular basis knows this. Why is it hard? Because coming back to the moment again and again is a true revolution against habit, a rebellion against our cultural tendency to always avoid what we are feeling and experiencing. It is this chronic avoidance of ourselves (not the rigorous practice of self-awareness we do on a cushion) that lies at the core of mindless consumer culture. Without having an actual practice, however, there’s no way Slavoj Zizek or any of the rest of us could really see the irony of this realization.
Incidentally, don't you love the photo in the linked article? It is so obviously a male model attempting to look like 'somebody meditating' but without any actual experience of what it is like to sit in meditation. It perfectly complements the article, in my opinion.
There is no way that meditation is an opium for anything. It is the exact opposite of escapism, it is facing the self with no distractions and no barriers.
