Personal understanding: Hua Yan Jing says, "We should observe the nature of the legal world and do everything with our heart." If you know that your money belongs to ill-gotten gains, you may silently donate money to do something beneficial to society and others with the consciousness of atonement and repentance, and maybe you still have some credit. However, if I am a rich man and I donate so much, I am a great master of merit. I promote it for my own fame and fortune, and it will have no merit, just as the wise master has shown.
