Righteousness
Man is a social animal. He has to exercise discretion. Everything heard and seen should not be repeated to anyone and everywhere. Once someone tells you something in confidence it should be like food digested and ingested. Some things are like secrets never to be told. Only those words should be uttered that do not harm anyone, words that hurt or insult inflicted on anyone or meaningless talk just harms and leaves wounds.
Once it is said that some religious man from another religion came to Bhikshu. They both conversed in private. After their talk they parted.
Muni Hemaraj from Acharya Bhikshu’s sect wanted to know the purpose of the visit of the other hermit.
All Bhikshu could say that the visitor wanted to repent about something.
Hemaraj Muni insisted on knowing about the other Sadhu's visit.
Acharya Bhikshu firmly and softly replied that it would be breaking trust that the other Sadhu had placed in him hence he could not say anything. Any breach of faith would be highly unprincipled. So Acharya Bhikshu refused to divulge any part of the conversation he had had with the Sadhu, even to someone from his own sect, who also happened to be his most desired student.
A person can only protect his principles if he promises to himself to be firm and strong. Oath to secrecy has to be respected and kept. If one is firm about something it will be groundwork for justice and clear in the long run.
It is rightly said - A wisely expedient person will indulge in criticism and praise, to suit himself or a situation, money goes and comes but a courageous person will stick to the path of justice and will never falter.
