Know that the state of one's religious and worldly affairs depend upon soundness of one's reflection. Anyone who has a share of it has an abundant share of everything good. It has been said : 'An hour's reflection is better than a year's worship.' 'Ali, may God ennoble his face, has said: 'There is no worship like reflection.' And one of the gnostics; may God have mercy on them all, said: 'Reflection is the lamp of the heart; if it departs the heart will have no light.'
