Blessings upon the birth of a son and his circumcision; circumcision as a mitzvah associated with happiness

[See Shabbos 130a which cites circumcision as an example of a mitzvah that the Jews accepted upon themselves with joy and continue to perform with joy.]

[There the Talmud cites an incident where a Sage added the phrase “In Whose dwelling there is happiness” in the introduction to the Grace After Meals at the feast of the circumcision, as is done in the introduction to Grace at a wedding. The Sages, however, state that his conduct should not be accepted as a basis for halachah, because a circumcision is not solely characterized by happiness, inasmuch as the child endures suffering.]

[After wishing that circumcision will infuse “joy into your dwelling,” the Rebbe cites the passage from the Talmud from which it appears that such a wish is inappropriate. In resolution, he cites these passages from Os Chayim VeShalom which quote these Talmudic references and explains that a circumcision should be carried out with great joy and celebration. Nevertheless, the celebration should not reach the level of happiness experienced at a wedding.]

[See Shabbos 88a, which states that because the Jews were compelled to accept the Torah, there were grounds for “a great protest” against its having been given to them.]

[See Vayikra 1:3 and commentaries.]
