Shunji Hosaka, "History of the Rise and Fall of Indian Religions" - A reference book to learn about the interrelationships not only with Buddhism, Hinduism, and Islam, but also with Sikhism and Jainism!
This book is a much appreciated reference for learning about Indian religions.
This book is unique in that it does not look at each of India's many religions separately, but focuses on their interrelationships.
The relationship between Brahmanism, Buddhism, and Jainism in ancient India. What was the background from which Hinduism and Islam grew in power over time? Why did Buddhism decline, and why has Jainism, which is said to be its sister religion, been able to survive today? This book is very valuable because it allows us to look at these questions from the historical background and the interrelationships among religions. Religion is not only religion. History, culture, politics, and economics are all involved. This book is a very stimulating work that allows us to feel the dynamism of such history.
