“It is vital and proper that chassidim should have the following three books in their possession: Keser Shem Tov, Or Torah and Tanya. For certain reasons, however, they should not be bound together in one volume. One should study them as much as one wishes (though let that study be worthy of the name!) — daily, or at least on Shabbos and Yom-Tov and at certain other times.”1
