Greetings and blessings,

I was happy to find out that your daughter, Ms. ..., became engaged to Rabbi .... May I express my blessings of Mazel Tov! Mazel Tov! May everything take place in a good and auspicious hour. May they build their home on the foundations of the Torah and its mitzvos as they are explained in the teachings of Chassidus.

Thank you as well for the good news that your grandson ... reached the age of three. Enclosed is a letter from my revered father-in-law, the Rebbe,1זצוקללה"ה, נבג"ם, זי"ע, with regard to the Jewish custom of cutting [the child’s] hair at that time.

May it be G‑d’s will that you always share good news regarding yourself and the members of your household, and also regarding communal affairs.

With blessings of Mazel Tov and for success in your affairs.

Menachem Schneerson

The connection of tzitzis to hair2 is explained in Pri Etz Chayim, Shaar HaTzitzis, and in Likkutei Torah, Parshas Shelach ([Bamidbar,] p. 47a). See also Rashi’s [commentary to the Torah, Parshas] Shelach, which cites the phrase3 “the hairs (tzitzis) of my head.”

The connection of tzitzis to marriage in holiness and purity is explained in the verse:4 “And you shall see [the tzitzis]... and not be swayed.” See also Menachos (44a) which states “his four tzitzis came [before his eyes].... Take possession of your acquisition.”5
