But we must have had some activity in order to have given our circulation a fair start before we can expect it to do its best when we are passive.
Then, what is most important, we must learn to drop all effort of our minds if we want to know how to rest; and that is difficult.

We can do it best by keeping our minds concentrated on something simple and quiet and wholesome.

For instance, you feel tired and rushed and you can have half an hour in which to rest and get rid of the rush.

Suppose you lie down on the bed and imagine yourself a turbulent lake after a storm.
The storm is dying down, dying down, until by and by there is no wind, only little dashing waves that the wind has left.

Then the waves quiet down steadily, more and more, until finally they are only ripples on the water.
