Meditation is like a single log of wood. Insight and investigation are one end of the log; calm and concentration are the other end. If you lift up the whole log, both sides come up at once. Which is concentration and which is insight? Just this mind.
Of course, you can’t force your mind to be silent. That would be like trying to smooth ripples in water with a flatiron. Water becomes clear and calm only when left alone.
It is the property of the religious spirit to be the most refining of all influences. No external advantages, no culture of the tastes, no habit of command, no association with the elegant, or even depth of affection, can bestow that delicacy and that grandeur of bearing which belong only to the mind accustomed to celestial conversation,--all else is but gilt and cosmetics, beside this, as expressed in every look and gesture.
