Context

“but few can put it into practice. Therefore the Master remains serene in the midst of sorrow. Evil cannot enter his heart. Because he has given up helping, he is people's greatest help. True words seem paradoxical. 79 Failure is an opportunity. If you blame someone else, there is no end to the blame. Therefore the Master fulfills her own obligations and corrects her own mistakes. She does what she needs to do and demands nothing of others. 80 If a country is governed wisely, its inhabitants will be content.” source
