The way sorcerers perform the recapitulation is very formal. It consists of writing a list of all the people they have met, from the present to the very beginning of their lives. Once they have that list, they take the first person on it and recollect everything they can about that person. And I mean everything, every detail. It's better to recapitulate from the present to the past, because the memories of the present are fresh, and in this manner, the recollection ability is honed. What practitioners do is to recollect and breathe. They inhale slowly and deliberately, fanning the head from right to left, in a barely noticeable swing, and exhale in the same fashion.

The inhalations and exhalations should be natural; if they are too rapid, one enters into something called tiring breaths: breaths that require slower breathing afterward in order to calm down the muscles.
Begin making your list today. Divide it by years, by occupations, arrange it in any order you want to, but make it sequential, with the most recent person first, and end with Mommy and Daddy. And then, remember everything about them. No more ado than that. As you practice, you will realize what you're doing.
