The greatest gathering, millions of people from around the world come to Karbala, yet too little is known about it and many never heard of it before. For anyone interested in reading about the annual Arbaeen walk, I highly recommend this book that explains it in a clear manner for all to understand. Regardless of the text, one can only truly know the meaning of the walk or the ziyara by experiencing it firsthand, and may we all be blessed to do so.
