There is (also) another kind which falls upon a person spontaneously. | At the beginning (stages) of this awareness which comes into being as a result of meditation — | the result of a love of (sound) doctrine and the exercise of devout conduct — | the mind is continually occupied as it meditates on something or other | every now and then, as a result of this excellent meditation | concerning the love of God and reflection on the things of God | the person who is occupied in such things out of love of (spiritual) exercise aimed at establishing his personal ministry (to God) | finds there is steadily born in him a faculty of spiritual vision of things. | Once his soul has been purified a little in devout ministry and alertness | then that spiritual contemplation of sight will every now | and then fall upon the soul without any concern on its part | at every moment this person will encounter in his mind some insight | and all of a sudden the mind will stand motionless | as though in some divine dark cloud which stuns and silences (the mind). | 7.1, p. 23
