The Tefila On The Tefila

We stand before the King of all Kings in a private audience during Shemoneh Esrei.  It is going really well and we leave Hashem with a long list of things we want including the most beautiful of all Brachos, the bracha of Shalom.  We finish the audience and we realize that Hashem would love to fulfill all of our requests.

The problem is that it is also up to us not to contradict what we claim are our foremost desires.  Lashon Hara is not exactly something that is spoken by a person who truly desires to lead a peaceful and harmonious life with those around him.

Mar Bar Ravina understood this.  He therefore composed a Tefila (see Brachos 17a) to say immediately after we finish saying the Bracha of Shalom.  “Elokai Netzor Lishoni Meira….”.  Hashem guard my tongue from evil and my lips from deceit.  To those who curse me, let me remain silent…

No doubt that one who says this with great Kavana will have his wishes for peace fulfilled!

“Zachor Eis Asher Asa Hashem L’Miriam BaDerech B’Tzaischem MiMitzrayim”

The Ramban and other Rishonim count among the Mitzvos Aseh Min HaTorah the mitzva of remembering and saying with your mouth each day what Hashem did to Miriam when she spoke about her brother Moshe.  The Chofetz Chaim in Shaar Tvunah Perek 12 says that being Mikayem this mitzva can save you from the aveira of Lashon Hara.  More than just saying the pasuk, says the Chofetz Chaim, one must think about the incident in order for it to have its intended effect.
