The afternoon following the funeral, the Rebbe called in his secretary, Rabbi Yehuda Krinsky, and among other things instructed him to establish, as quickly as possible, a tzedakah-fund to be named for the Rebbetzin, of righteous memory.
Before the end of Shiva, "Keren Hachomesh" was established (an acronym of the first letters of the names Harabbonis Chaya Mushka Schneerson) at Lubavitch World Headquarters, which continually serves a variety of needy causes, primarily women's social and educational purposes.
During the following years, the Rebbe distributed significant sums from this fund to both institutions for women as well as individual women in need of help all over the world.
Sunday, the 24th of Adar, 1988, was marked by the laying of the cornerstone for "Campus Chomesh," in memory of the Rebbetzin. Near the conclusion of the momentous event, the Rebbe himself suddenly arrived.
From the car window the Rebbe handed Rabbi Avraham Shemtov 470 dollars (numerically equivalent to "Chaya Mushka") saying, "I am on the way to the Ohel, and I shall visit her (resting place) as well. Tonight is her birthday, and this (sum) is my participation and her participation in this new edifice."
