There are a million ways to relax in this modern era. Yoga, taichi, zen koans, transcendental meditation, knitting, and yes, video games. It might seem odd to mention video games in the same sentence as "zen" or "meditation," but think for a moment: most forms of meditation involve focusing on one simple thing, such as the flame of a candle, or the repetition of a mantra, and excluding all other thought. Doesn't World of Warcraft call this grinding?
Now, granted, there are plenty of complicated and interesting things to do in WoW that involve lots of concerted thought and could not be considered meditation. But couldn't grinding away on daily quests or farming for materials be considered a very modern way for some people to wind down, clear their mind of daily frustrations, and just be nothingness itself for a little while? I know for my part, playing WoW by myself for a while certainly isn't ecstatic communion with the divine, but it can be a great way to just put everything else away for a bit and come back to life feeling refreshed.
What do you think: is grinding a form of meditation for you, or is it just something to do when you're bored out of your mind?
