Does anyone have suggestions about meditation or breathing exercises to replace the usual crap people do when they want to zone out for a bit (television, reading a half dozen random articles online, dumb anti-social networking apps, etc)? Watching some dumb TV show or reading a random news article that will just get thrown on the pile of miscellaneous mental junk doesn't feel particularly restful, pleasurable, or useful (at least to me).
Personally, I have tried mindfulness meditation (find it very hard to do without a guide) and "shamanic" meditation (using that name loosely -- just listening to drums in a dark room, having a "waking dream" of sorts. My subconscious knit together some interesting stuff while doing this, but I stopped being able to do it when I OD'ed on NSI-189 and haven't gotten it back). However, both these techniques generally require a specific environment and a set amount of time. I'm looking for suggestions that can be implemented anywhere. Such practices would be of general interest to the forum as well.
There are a ton of articles online, but I figured this community would have more experiential wisdom to share than most.
