Chazal say that all our pain is caused by the Accusing Angel who constantly prosecutes us before Hashem.
Is there anyway to protect ourselves from his constant accusations?
Yes! Because the Chofetz Chaim explains that Hashem only listens to lashon hara about those who speak it themselves. If a person does not speak any lashon hara, Hashem will not let the Soton open his mouth to prosecute us.
So, how do we protect ourselves? If we refrain from lashon hara the Heavenly prosecutor will not be allowed to speak.
