O the consolation of being able to thrust aside and cast into oblivion every tiresome intrusive impression and in a trice be utterly at peace!
When I read this, I tend to interpret “impression” as “opinion” which may or may not be the correct interpretation. My first thought on reading this meditation is, “how often does that ever actually happen?” People carry around the baggage of not only their own opinions (which may be based off of mistaken information, ignorance or confusion) but also the opinions of others, either positive or negative. They are constantly arguing with these opinions. How do you go about thrusting them aside or casting them into oblivion? How do you know when an opinion is based on hearsay or incorrect information, and how do you correct it, for yourself or someone else.
