Yoga as philosophy and religion

"Yoga as Philosophy and Religion" by Surendranath Dasgupta is a scholarly examination of the philosophical and religious aspects of Yoga, composed in the early 20th century. The work delves into Patañjali's Yoga-sūtra and its subsequent commentaries, aiming to elucidate the foundational doctrines of Yoga, as well as its implications in philosophical and religious contexts. The text likely appeals to readers interested in the deeper intellectual explorations of Yoga beyond its physical practices. The opening of the book establishes the context of Yoga as not merely a set of physical exercises but a profound philosophical tradition with a rich historical background, rooted in metaphysics and ethics. Dasgupta introduces key concepts from Patañjali's teachings, emphasizing the distinction between mental and physical phenomena through the lens of the three gunas: sattva, rajas, and tamas. He presents a framework for understanding the evolution of these concepts, discussing the nature of reality, the existence of an external world, and the relationship between purusha (spirit) and prakṛti (matter) as central themes that will be further developed in the subsequent chapters.
