And Abraham came "Lispod L'Sarah Vi'Livkotah" (Bereshit 23:2) (to eulogize Sarah and to weep over her.) In regard to the writing of the word Vi'Livkotah in the Torah we find something very interesting. The letter "kaf" is smaller in size than all the other normal letters of the Torah! Why this variation? When Sarah died, Abraham did not mourn excessively. He realized that her death, sorrowful as it was, was not a tragedy, for Sarah had lived a full and rewarding life. She had accomplished much during her stay on earth and her good deeds were innumerable. She had aided Abraham with his devotion to Chesed by opening her house to as many guests as possible and by taking care of all their needs.
Because of her outstanding righteousness, Hashem bestowed upon her special personal qualities. In fact, we are told that in terms of prophecy she was even greater than her husband Abraham. Therefore, the small "kaf." Abraham definitely mourned and wept over Sarah but not in an excessive fashion. The loss was great but the comforting realization of her fulfilled life made it much easier to accept. Those who, like Sarah, spend their lives assisting others benefit in both this world and the World to Come. Their memories are cherished fondly and their good deeds and accomplishments are cherished and commemorated forever. On the other hand, those who become negatively influenced during their stay on this earth are both vilified by later generations and suffer in the World to Come.
