The real purity is experienced not by means of the outer ablutions nor by keeping away evil thoughts, but by keeping the heart pure from feelings which disturb the rhythm of the mind and thus upset the whole spirit. Feelings have a greater power than thoughts. If evil thoughts are monsters evil feelings are as demons. Such feelings as the desire of robbing someone of his rights or his belongings have a very disturbing effect upon the spirit. Before such a feeling is put into action the effect is more, while it is being put into action it is less, but afterwards the effect is most. Life rightly and honestly lived has inner struggles, but by adding to it feelings that disturb life's tranquility one only adds to one's troubles in life, which then become endless.
