Birchas Kohanim & The “Yehi Ratzon”
ותתננו לאהבה—כשם שנתת את יוסף צדיקך בשעה שהלבישו אביו כתונת פסים לחן ולחסד ולרחמים בעינך ובעיני כל רואיו
The obvious question is: what kind of Chen was there at the time when Yosef received the Kesones Pasim? On the contrary, this seemed to be the very reason for the hatred of the brothers.
I asked this question to Mori V’Rabi Hagaon R. Shlomo Miller shlita.
His answer was that one cannot ask questions on this Tefillah.
R. Shmuel Salant zt”l claimed this to be an unreliable Tefillah.
The Earlier Sources
The מהר"ם מרוטנבורג, תרומת הדשן, מהרש"ל, רמ"א, לבוש, דרישה, של"ה, ב"ח, תוס' יו"ט, מג"א and ט"ז all hold to say the Ribono Shel Olam for dreams three times.
(The final time being at “Shalom.”)
It makes sense to say it three times rather than two. To undo a neder we say three times “Mutar Lach.” Undoing bad dreams as well should similarly be said three times.
The Source of the Printed “Yehi Ratzon”
The Tefillah of “Yehi Ratzon” printed in many of today’s Siddurim comes from the Shaarei Tzion of R. Nosson Nota Hanover.
The Shaarei Tzion is a collection of Kabbalistic tefillos. R. Nosson Nota Hanover writes in his Hakdama that these tefillos were taken from the writings of R. Chaim Vital based on the teachings of the Arizal.
However, in both seforim from R. Chaim Vital — Pri Eitz Chaim and Shaar Hakavonos — the Arizal is quoted differently.
There is no mention there of the “Yehi Ratzon.”
