The heart is important, not the superficial actions. Many people pursue spiritual practice, but some say, "I have practiced so arduously, yet I have gotten nothing in return." Possibly they have not been sincere enough. We should not blame God, we should not lose faith in the Buddhas and Bodhisattvas, nor should we doubt our Master. Instead, we should introspect to see whether we have any places or knots that have not been untied. If we have great sincerity, all results will come to us. Even when sometimes we think we are not sincere, still we have to persist in practicing, and rectify it bit by bit. One day the world will give us the sincerity. Sometimes, we are ill, we are in agony, in pain or a bad mood -- all these unhappy situations will wake us up. Therefore, we still have hope.
