In this fascinating book, Rabbi Zvi Ryzman of Los Angeles deals with a fascinating array of modern halachic dilemmas – and deals with them in a fascinating way. In response to Covid-19, what is the status of backyard minyanim? Before long, artificial meat made from stem cells will be on the market – what is its kashrus status? May one desecrate Shabbos to save property from looters? May one daven from a cell phone? Rabbi Ryzman discusses these and many other relevant questions by marshaling a dazzling array of halachic sources, from Talmudic, halachic and contemporary sources. Brilliantly – often surprisingly – he shows how classic sources apply to today’s situations. He weaves them all together in tapestry that is engrossing and extraordinary. The depth and quality of the reader’s understanding of the halachic process will be astoundingly improved. This book is unique and its author is a marvel. Zvi Ryzman insists that he not be called a rabbi, although he is in the top rank of Torah scholars. He calls himself an ish asakim, a businessman. Indeed, he is the embodiment of the Rabbinic teaching that one should combine Torah with commerce — yet he gives priority to the beis midrash over the office. Reb Zvika is a scholar, teacher, lecturer, author, and philanthropist. He is a winner of the Jerusalem Prize for his many Hebrew volumes of Ratz KaTzvi. His halachah shiurim in Israel and America are attended and acclaimed by renowned rabbinic leaders. He has a fertile mind, is an original thinker and has a passion to share his brilliance with others, through the written and spoken word. In this extraordinary book, he educates and stimulates – and shows us that halachic principles are eternally enlightening.
