Rav Chaim Kanievsky often advises people to learn a Gemara relevant to what they are suffering from. He may advise someone with a malignant growth to learn Bechoros, which discusses many different diseases; someone with foot problems to study perek Keitzad Haregel of Bava Kama; or someone who cannot find his beshert to learn Kiddushin.
“Everything that makes a person learn more Torah is itself a segulah to save him, because Hashem wants man to come closer to him,” Rav Chaim explained. “A person who needs deliverance is more willing to accept things. So I advise him to learn something and, with Hashem’s help, it’s effective.”
Recently, Rav Chaim was visited by someone suffering from severe headaches. He advised him to learn the Rosh’s commentary on Shas.
