True sincerity is said to be the truth of heaven. Causality is also said to be the truth of heaven. What is the relationship between causality and true sincerity? The principle of causality states that good thoughts and behavior results in joy, while evil thoughts and behavior results in suffering. True sincerity is a mindset that continues to be free of greed, arrogance or self-love, even in times of suffering or inconveniences.
By practicing true sincerity, we erase the negative cause of our suffering or obstacle; by the principle of causality, we then create joy in the future. But most of the world when faced with suffering or obstacles do not understand causality, and tend to react negatively, continuing the cycle of suffering. We blame others for our sufferings and continue to create a future of despair.
But this path of true sincerity is a difficult path. Who of us have the strength to lean on God and accept the obstacles and sufferings and have a positive attitude? Many of us can promise to be good, but how difficult is it when faced with sufferings. How easy is it to control our tempers when others attack us unfairly? How difficult is it to accept a death of a child? How easy is it to accept discrimination without anger, hate, or retribution? These are difficult situations, but they arise from our past actions. We must have faith in God, but we must also understand causality. Causality gives everyone the opportunity to have joy in the future. Causality and true sincerity are the truths of heaven.
