By a wrong attitude, therefore, a person accumulates in his mind undesirable impressions coming from people, since no one in this world is perfect. Everyone has a side which can be criticized and wants repairing. When one looks at that side, one accumulates impressions which make one more and more imperfect because they collect imperfection; and then that becomes one's world. And when the mind has become a sponge full of undesirable impressions, then what is emitted from it is undesirable also. No one can speak ill of another without making it his own; because the one speaking ill of others is ill himself.
