it's not that simple. (neither meditation nor Aspergers [high-functioning autism].)
there are at least a hundred[0] traditional techniques for meditation. one needs to find those that work. for someone with a highly monotropic autistic trait techniques that work with a singular focus are probably more well-suited, while someone with "kind of the opposite" (hello ADHD people) should try those that are more cognitively active, have mindfulness elements, and build rich imaginary worlds.
