Conscience is the first law of God, which He deeply carved in the hearts of the First Created, and consequently, each one of us takes it as a "photocopy" from his parents when he is born. Those who have managed to sensitize their consciences through the daily study of themselves feel themselves estranged from this world; and, as a result, worldly people are dumfounded by their discerning behavior. Those, however, who do not examine their consciences are neither benefited by spiritual study nor by the advice of the Elders, nor are they even able to keep God’s commandments, since they quickly become insensitive.
