Conscience

Almost every culture in our history has recognized the existence of that faculty of the mind which nags us with the feeling of obligation to do "right".
Ancient Egyptians were urged not to transgress against the dictates of the heart, for one "must stand in fear of departing from its guidance."
Hindus considered conscience to be "the invisible God who dwells within us."
Quakers emphasize conscience in responding the "inner light of God."
Some Christians believe that conscience is the Counselor that Jesus promised his diciples.
