All day, the world pours into you: a colleague’s tone, a driver cutting in, bad news, a compliment, an ad. The tradition calls these impressions. They are a kind of food.

Received asleep, an impression goes straight to a self. The insult reaches the anger before you know it, and the anger takes the day. Received awake, the same impression can be met, seen and let go. Then it feeds your consciousness instead.

This is a practice the tradition treats as central. Its moment is tiny: the half second when an impression arrives, before the reaction. The tradition calls waking in that moment a conscious shock. You do not suppress the impression. You remember yourself in front of it.

This gathers much of what you have practiced. The door question keeps you present. The pendulum of page 13 shows the swing beginning. Catching a self (page 21) names who is about to react. Here they meet, in the middle of a real day, at the moment that matters.

It will often fail. You will react first and notice later. That is still progress. The noticing comes sooner each time, until one day it comes in time.
