Ein Ayah (Hebrew: עין איה) is a commentary on Ein Yaakov - a compilation of all the Aggadic material in the Talmud - by Rabbi Abraham Isaac Kook, [1] the first Ashkenazi chief rabbi of British Mandatory Palestine and founder of Yeshiva Mercaz HaRav Kook.
The commentary is presented in numbered paragraphs corresponding to the Talmudic text, and it expands upon many diverse subjects in an allegorical style.
Among other things, Rav Kook presents a historical and philosophical view of the Second Temple period, during which rabbis and Talmudic scholars faced significant persecution from Roman authorities.
The print edition of the book comprises four volumes, which speaks to the large amount of content in Ein Yaakov.
At the end of his life, Rav Kook began to write another edition of the book, which included an interpretation of three pages of the Gemara.
