**ושמחת בחגך.**ואמרו רבותינו ז"ל (בפסחים דק"ט ע"א) אין שמחה אלא בבשר, עיין לעיל פ' בראשית בהגה ע"ה מה שהעתקתי בשם הבעל שם טוב: (מספר תפלה למשה בהקדמה).
And you shall rejoice in your festival. (ibid. 16:14) There is no rejoicing except with flesh.⁹ 109a. That is, except when eating meat, as the verse says: “And you shall sacrifice peace-offerings, and shall eat there; and rejoice before the L-rd your G-d” (Deuteronomy 27:7). That is, there is no joy Above other than that which rises from below, from flesh and blood.¹⁰ Tefilah l’Moshe, Hakdamah
footnotes: ⁹ Pesachim ¹⁰ That is, the greatest joy in heaven is when creatures of flesh and blood serve G-d from earth.
