You have walked the day backward each night since page 17. Now the review gains a purpose.
Before, you watched the whole day like a film, as a witness. Now, as you go backward, you look for particular moments: the ones where a self took the wheel. The sharp reply at dinner. The hour lost to a screen. The small lie at work. The flash of envy that passed so fast you nearly missed it.
You will find that the review shows you more than the day did. In the moment, the self was invisible, because you were it. At night, with a little distance, you can see it clearly. This is why the review is one of the best tools for the first step. Anything that happened can be used.
When you find a self, do not stop to wrestle with it. Mark it and keep going. If one moment stands out, you can come back to it in the meditation from page 30. In this way the practices of this part join together. The review collects. The meditation understands. The request lets go.
Keep a small notebook by the bed. A word or two for each self you found is enough. After a few weeks, read it back, and you will see which selves come most often. That is your map.
