Counting the Omer is a Kabbalistic meditation guide to understand the in-depth meanings of each of the forty-nine days between Pesach (Passover) and the Shavuot celebration of the revealing of the Torah. Rabbi Kantrowitz follows Kabbalistic guidelines to show how the unique values of the sephirot interact each day, giving the reader insight into the strengths of the day. Through this guide the reader is led to meditate on the mystical qualities of life and self.
This is one of my favorite Jewish books, and the top book on the Omer - trust me, I've looked! I read it once a year, while I'm counting the Omer, and each year it is fresh and brings me new perspectives on myself, the Omer, and how to proceed for the coming year. I don't know how Rabbi Kantrowitz managed to write meditations that are different, fresh, and profound for 49 days - but she's done an amazing job!
Also, if you miss a day, it's not the end of the world and you don't feel that you can't get "back on the wagon" in terms of daily meditations. I would heartily recommend this book to anyone, including people who are interested in converting to Judaism and those who don't consider themselves spiritual seekers - although Rabbi Kantrowitz is a post-denominational Rabbi, this book is perfect for anyone of any denomination!
