I think almost everyone who gets into meditation eventually develops their own library of micro-practices. These are performed alongside the main practice you do, or implemented as parts of it. You grow a forest of mental maneuvers that help you see the world differently, surface dormant emotions, or whatever you want to do. Most of the time these micro-practices are not written down. But here are some of mine.
Include everything
Widen or morph the shape of your attention by including everything possible. The back of your head, the air blowing behind it, the far wall. Notice that those can fit in the field of attention without effort. Notice that, simultaneously, you can include, within the field of attention, your concept of “the whole visible universe” and “all of your memories”—these concepts are mental sensations. See how the most seemingly solid sensation is something flickering, ephemeral, just like the sensory reports from the wind on your face. If there is any strain in this, include that sensation, too.
