The Ben Ish Hai (בן איש חי) is a standard reference in some Sephardi homes (functioning as "a Sephardi Kitzur Shulchan Aruch") and is widely studied in Sephardi yeshivot. Due to the popularity of this book, Hakham Yosef Hayim came to be known as "Ben Ish Hai", by which he is referred to by many today. The book is a collection of homilies he gave over two years discussing the weekly Torah portion. Each chapter begins with a mystical discussion, usually explaining how a Kabbalistic interpretation of a certain verse relates to a particular "halakha", and then continuing to expound on that halakha with definitive rulings.
