Letter handwritten and signed by R. Avraham Yeshayah Karelitz, who signed in his usual manner with the acronym: "A.Y.Sh." (read Ish). [Bnei Brak, ca. 1940s].
The Chazon Ish begins by relating to the words of the letter-writer, who presumably apologized for not hiding from the Chazon Ish unfortunate experiences which occurred to him: "There is nothing inappropriate with the fact you didn't hide things from me, though it is obviously much better to inform me of joyous occasions". He then responds to several Torah topics, and urges the writer to continue investing effort in Torah study: "Be strong and courageous, grab and eat…".
After his signature, the Chazon Ish adds two lines, in which he encourages the person to perform an act of kindness with himself and go on vacation for a month: "Perhaps you can go on vacation for a month to recover, please make an effort in this direction and request of your soul to perform an act of kindness to your body".
R. Avraham Yeshayahu Karelitz (1878-1953), author of the Chazon Ish, a foremost scholar in Halacha and Jewish philosophy in our generations. A preeminent Torah scholar and hidden righteous man, his first book Chazon Ish was published in 1911 anonymously, and he thereafter became known under that title. He immigrated to Eretz Israel in 1933, where he became recognized as the leading Torah authority, and stood at the helm of the resurgence of the Torah world in our generation. He authored and published numerous volumes of Chazon Ish, which were written with great toil and in-depth study, covering nearly all Talmudic topics.
