One man felt that he had the answer, and so he came to the home of Rav Yisrael Salanter. Rav Yisrael sat and patiently listened to this man's description of the bad deeds of his fellow Jews. The Rav's wise reply to the man was as follows. Since you consider yourself such an expert in finding faults, you should leave the community and go into isolation. Then you will have time to think and contemplate your own faults.
Isolation is a terrible punishment.
No smiles, no hello or goodbye. No one to play with or to tell secrets to. We have neither tzoras nor isolation, but we should still take the time to consider the seriousness of loshon hora and the damage that it causes.

Those new students disseminated the Torah.
