[4] Pliskin's father, Rabbi Shmuel Pliskin, had been a student of Israel Meir Kagan, popularly known as the Chofetz Chaim, at the Raduń Yeshiva in Poland and had written a Yiddish-language biography of him, Der Chofetz Chayim: Zine Leben un Shafen (Warsaw, 1936).
[6] In 1974, after writing an article for The Jewish Observer about the life of the Chofetz Chaim, "The Profile of an Oheiv Yisroel," Zelig Pliskin was asked to write a book explaining the Chofetz Chaim's teachings.
After Pliskin's move to Israel, the outreach organization Aish HaTorah asked him to speak on human emotions and relationships.
Pliskin now provides marriage counseling and works with individuals to encourage their personal growth and improvement.
He remains closely affiliated with Aish HaTorah, and lectures both in Israel and in the United States.
