Firstly this thread is intended only for those that believe or are open to the idea that enlightenment is the spiritual realization of Nirvana/moksha/whatever you want to call it.
Okay so we know insight meditation is a key ingrediant, but another important attribute to attaining enlightenment is training one's awareness, or mindfulness. Mindfulness allows one to both play their part in the world and observe themselves playing that role from a dual perspective. It is complete awareness of the world around oneself, allowing all sensual activity to flow in and be processed, but not judged. For more on this I'm sure a member can link people into a full synopsis.
Not only does mindfulness allow one to see their world without filters like prejudice, it also makes it easy to retain concentration during meditation, speeding the journey considerably, hence why many masters stress the importance of training one's concentration and mindfulness at the same time.
Athletes have another term for mindfulness, they call it being in the "zone." If you've ever been in this state of mind you know it is a state of total reaction, without judging the world or letting your perspective get distracted by your consciousness.
This is where videogames come in, as in training oneself in mindfulness they can train themseves to go into the "zone" at any time. I won't go into detail exactly how to make this shift in your state of mind willful because its hard to explain and my terms are personal. I think of it as just replacing my train of thought with the videogame world, but that's easier said than done and you should find your own terms to see what mindfulness is and how to get yourself there. The important thing, though, is practice, and games provide such practice, not to mention it makes you a lot better at the game.
