As soon as a sefer book is made from the very, very lofty and wondrous Torahs

Likutay Moharan II, Torah 36: As Soon as a Book Is Made from the Lofty and Wondrous Torahs As soon as a sefer [book] is made from the very, very lofty and wondrous Torahs [teachings], since it is made into a sefer, there are coverings and concealments upon them, that their pure and wondrous light is covered and concealed, and the pages of the binding cover them, and so forth.
