Thanks. Are you referring to the phrase: “I crossed over the flood without pushing forward, without staying in place”?
You then mentioned “should not get caught up…”–I think that is important, and that beginning meditators may not be able to do that. They are at risk of engaging in mental proliferations around signs/features of external stimuli. For this reason, I wonder if the common contemporary practice of encouraging “choiceless awareness” is the wrong thing for a beginner.
