Input (English): Near the beginning of this book the author states that it is devoted to a true understanding of the fiqh or law. The explanation of ma'aseh merkabah is intentionally scattered throughout the book as chapter headings, and to avoid transgressing the prohibition against revealing the secret teaching to man, the book is purportedly addressed as a letter to the author's student Joseph. Contrasted with the author's commentary on the Mishnah Torah, this work is intended to explain the underlying meaning of the Biblical writings. FTP, identify this Arabic text written for the confused by Maimonides.
