This book is part of a series exploring the most widely practiced religions. I found it in my building's informal book swap when I lived in Brooklyn and have been carting it around for more than a decade. I have long been fascinated with the practice of Buddhism and finally committed myself to reading it. The book spends a lot of time tracking the spread of Buddhism across the continents and the centuries (skimmed it). This is not to be confused with a "primer" on Buddhism. It is a dense academic deep-dive with extensive quotes from religious texts and the evolution of the Buddha. The dry text was less than inspiring to push through and I put the book down a few chapters in. Another reader who has more historian leanings my find this exploration fascinating; I will gladly share with you my hardcover.
