Minchas Yosef, Tefillah, Yosef Ingber (Hebrew)

This Sefer, by Rav Yosef Ingber, the author of "Chalonei HaBayis," is a sweeping and splendid commentary that explains the formation of the Tefillos in an amazingly clear fashion, from Mah Tovu until the end, including the Tefillos of Shabbos and Yom Tov. The Sefer also explains the reason for each Tefillah, the subject of the Halachos of Tefillah and the Beis HaKnesses, additional Tefillos, Kerias HaTorah, and Birkas HaMazon, all based on the words of Chazal and the Midrashim, with additional explanations, insights, and indices.
