Divine meditation.

The Art of Divine Meditation by Joseph Hall

Joseph Hall endeavored to teach the art of meditation. It is a heavenly business that does benefit the soul! 

Joseph tells us that it is wrong to conceal meditation from many, for its benefit may  be universal.
This is the kind of meditation pursued by the divine psalmist who upon viewing the glorious frame of the heavens was led to wonder at the merciful respect God had toward so lowly a creature as man.

His view is that 'some of the ancient monks proved so excellent in this divine business because they intermixed bodily labour with their contemplations! 

Joshua 1:8

Keep this Book of the Law always on your lips; meditate on it day and night, so that you may be careful to do everything written in it. Then you will be prosperous and successful.
