Negative thoughts, big or small, have a huge impact on your mind. A mind that is flooded with negative thoughts is absorbed by selfishness. You must stop the flow of negative thoughts. You can do it through introspection and repentance. Repentance is essential as the sincerity behind your effort to improve. It should come from the bottom of your heart, from the core of your inner being for positive and lasting change. ¶ by Zen Master Miao Tsan
