Therefore they should be trained or urged to forethink or reflect seriously and often on the cure or process proposed.

This is the setting of the nail, which is to be driven in by suggestion.

The other method is where we act entirely for ourselves both as regards previous preparation and subsequent training.
I here repeat, since the whole object of the book is that certain facts shall be deeply and _clearly_ impressed on the reader's mind, that if we _will_ that a certain idea shall recur to us on the following, or any other day, and if we bring the mind to bear upon it just before falling asleep, it may be forgotten when we awake, but it will recur to us when the time comes.

This is what almost everybody has proved, that if we resolve to awake at a certain hour we generally do so; if not the first time, after a few experiments, _apropos_ of which I would remark that "no one should ever expect full success from any first experiment." Now it is certainly true that we all remember or recall certain things to be done at certain hours, even if we have a hundred other thoughts in the interval.

But it would seem as if by some law which we do not understand Sleep or repose acted as a preserver and reviver, nay, as a real strengthener of Thoughts, inspiring them with a new spirit.
