Line-by-line transliterated and translated Hebrew seeks to balance the beauty and intensity of the Hebrew text with an easily understood English. Commentaries from a wide range of sources explain difficult passages in the siddur and involve the reader in the emotional, spiritual and inspirational experience of prayer. The editors explain the reasons for many of the additions and changes that distinguish nusach Sefard from nusach Ashkenaz. Clear instructions for following the synagogue service as well as for ritual observances in the home are provided throughout. More complex or lengthy halachot (laws) are discussed in the 'Laws" section at the end of the siddur. This siddur has become the standard against which others are judged.
