This book is an introduction to Patañjali's Yoga Sūtras and its core concepts about the self, suffering and consciousness. It highlights its relevance to contemporary theories and applications in the fields of psychology and health.

The book adopts sociology of knowledge as a broad framework as it delves into the core concepts of yoga psychology in the Yoga Sūtras in the context of worldviews and frameworks present in the Upanisads and the Sāṁkhya system. It provides an interpretation of Kriya Yoga and its practice in pursuit of spiritual upliftment, and concept of Samādhi or the transformation of consciousness using the language and idiom of contemporary psychology. It draws parallels between yoga psychology and the ideas of Husserl, Jung and Piaget while reconciling the seemingly disparate cultural, religious, spiritual, and intellectual traditions of eastern spirituality and schools of modern psychology. The book also discusses yoga psychology in relation to psychoanalysis, radical behaviorism as well as mainstream, cognitive, humanistic, transpersonal and indigenous psychologies and provides a guide to both the theories of yoga psychology and its applications.
