Divrei Mishkan HaNefesh is like a midrash on the machzor, a "Mishkan HaNefesh Rabbah." This volume serves as a springboard for entering into the sanctuary of our souls with enthusiasm and helpful insights, exegetical and homiletical material, tips and guideposts as well as indexes of poems and of biblical citations. This book focuses on the prayers and scriptural offerings included in Mishkan HaNefesh. Rubric by rubric, insights are presented with background information concerning the perspective and choices of the editors, as well as an offering of extra material to engage the reader. A number of brief essays, composed by members of the machzor editorial team, are also included.
