Shalom u'Vrachah!

In response to your letter from the 22nd of Adar, as you requested, you and all those you wrote about will be mentioned at the holy resting place of my revered father-in-law, the Rebbe, of blessed memory. Surely you are aware of the three daily study portions established by my revered father-in-law in Chumash, Tehillim, and Tanya; may you keep them at least from now on.

As we approach Pesach, may you celebrate it with your entire family in kashrus and joy.

Blessings, in the name of my revered father-in-law the Rebbe shlita,
Mazkir

P.S. Regarding what you wrote about "Shit Alfei Shanei De-havi Alma" (the six thousand years that are the world) corresponding to the six middos—each middah includes all others, and from this you deduce to divide each millennium into seven parts: It is true that vav (six) corresponds to the six middos (see Zohar I 116b and there in many places). However, although in several matters each middah is included within seven middos—as in Sefiras HaOmer, Yovel, Ana B'Koach, etc.—because mochin (intellect) are concealed there; nevertheless, dividing a millennium is either into ten (each one consisting of yud times pei yud = 100) or into twelve hours (see Pirkei D'Rabbi Eliezer ch. 7 and 48; also see Sefer HaLikutim to Shemos 1:14).

Summary

The Rebbe explains that while mystical structures often use sevens due to inclusion of qualities within each other, when dividing world history's six thousand years it is more accurate to use divisions of ten or twelve as found in classical sources. Consistent Torah study and joyful observance are also emphasized.
