There is no literal physical path to walk in this “game.” It is not an avatar facilitated game other than in the beginning where you setup the conditions for entry via non-dogmatic meditation.

“Navigate to the cave of solitude,” says the game helping gnome, “to proceed to the next level.”

Finding a suitable environment for meditation involves minimizing distractions and creating a space that fosters stillness. Think of this as your figurative “gaming room” except you have to unplug technology, both electronic and organic (mind & body). Ideally, this means seeking out a location with fewer stimuli—like a quiet darkened room—where you can focus inward with eyes closed. It can also be a literal cave…

However, it's important to remember that complete silence is rarely attainable. For instance, if a lawnmower starts up in the distance, or any other distraction, learn to be accepting of it as it is as opposed to desiring it to go away or attempting to avoid it in some other way. This is a “game” that is dependent on the accumulation and application of wisdom. You should store this in your loose-grip perspective:

Life is filled with “lawnmowers,” and your mind is in no shortage of supply, meet them with the right view (level 3 & 4 pending) and sensory settings. They are actually needed, figuratively, in order to progress. They hone your neutrality, wisdom and concentration skill settings. Still, reduce down the sensory inputs with a quiet de-stimulating environment.
