“We must guard our conscience on three points—with respect to God, with respect to our neighbor, and with respect to things. One guards his conscience with respect to God when he avoids the various sins. He guards his conscience with respect to his neighbor when he does not grieve him, judge him, slander him, scandalize him, or push him towards evil deeds. He guards his conscience with respect to things when he does not cause destruction or damage to material things through carelessness, negligence, or unscrupulousness.  The greatest wealth is obtained when one strives to preserve his conscience unburdened. But in the event that he senses that something has wounded him, he should correct it immediately, and thus he will return to his prior state.”
