Here are the basic Instructions:
Whenever all or part of a sensory experience suddenly disappears note that. By note I mean clearly
acknowledge when you detect the transition point between all of it being present and at least some of it
no longer being present.
If you wish, you can use a mental label to help you note. The label for any such sudden ending is “Gone.”
If nothing vanishes for a while, that’s fine. Just hang out until something does. If you start worrying
about the fact that nothing is ending, note each time that thought ends. That’s a “Gone.” If you have a
lot of mental sentences, you’ll have a lot of mental periods – full stops, Gones
