These memories, written by R. Hayyim Simhah Leiner, preface the family history he compiled and first published in 1909. The grandfather of his childhood is Rabbi Yaʻakov Leiner, whose teachings are the subject of this book. R. Yaʻakov (1818-1878) was the rebbe and spiritual leader of a community of Hasidim in Izbica and then in Radzyn, located in the Podalski region of Congress Poland for over 24 years ... The discourses and insights he shared throughout his life were gathered by his sons and grandson in four large volumes entitled Beit Yaʻakov (The House of Jacob.))
