The book explores ethics and comparative religion, emphasizing the crucial role of duty in human society. An ordered societal structure relies heavily on duties and obligations. However, most people today either lack a sense of duty or have a weak understanding of it in social, political, economic, ecological, and religious contexts. This deficiency has led to a critical global situation. Therefore, understanding the strong sense of duty and commitment often found in individuals devoted to religious and spiritual ideals is essential. This understanding can also highlight a fundamental aspect of religious and mystical traditions: the realization of similar mystical truths independently across different times and places.
