Beginning with today, we will have a series of review periods. Each of
them will cover five of the ideas already presented, starting with the
first and ending with the fiftieth. There will be short comments after
each of the ideas, which you should consider in your review. In the
practice period, the exercises should be done as follows:

Begin the day by reading the five ideas, with the comments
included. Thereafter, it is not necessary to follow any particular order
in considering them, though each one should be practiced at least once.
Devote two minutes or more to each practice period, thinking about the
idea and the related comments. Do this as often as possible during the
day. If any one of the five ideas appeals to you more than the others,
concentrate on that one. At the end of the day, however, be sure to
review all of them once more.

It is not necessary to cover the comments literally or thoroughly in the
practice periods. Try, rather, merely to emphasize the central point,
and think about it as part of your review of the idea to which it
relates.

The review exercises should be done with your eyes closed, and when you
are alone in a quiet place, if possible. This is emphasized particularly
for reviews at your stage of learning. It will be necessary, however,
that you learn to require no special settings in which to apply what you
have learned. You will need it most in situations which appear to be
upsetting, rather than in those which already seem to be calm and quiet.

The purpose of your learning is to enable you to bring the quiet with
you, and to heal distress and turmoil. This is not done by avoiding them
and seeking a haven of isolation for yourself. You will yet learn that
peace is part of you, and requires only that you be there to embrace any
situation in which you are. And finally you will learn that there is no
limit to where you are, so that your peace is everywhere, as you are.

You will note that for review purposes the ideas are not always given in
quite their original form of statement. Use them as they are given here.
It is not necessary to return to the original statements, nor
to apply the ideas as was suggested then. We are now emphasizing the
relationships among the first fifty of the ideas we have covered, and
the cohesiveness of the thought system to which they are leading you.
