Whether or Not One’s Prayers are Accepted Depends on How he Speaks

Whether or Not One’s Prayers are Accepted Depends on How he Speaks:

Sefer Ye’aros Devash (Chelek 2, Drush 9) writes: “Woe to us! How could our prayers and learning be desirable to Hashem if our tongues are filthy with the dirty sin of lashon hara, and are also used for words of nonsense, mockery and jest and speaking to women? One aveirah leads to the next. Save yourself from being judged for this, as there is no mercy in the judgment.”
