The Upanishads as a Source of Depth in Yoga Teaching This book is not mere theory nor is it a spiritual retrospective on times past. It is a bridge: between ancient wisdom and contemporary yoga practice. Between silence and language. Between philosophy and lived experience. The Upanishads, over 2500 years old, are among the most powerful texts of spiritual self-knowledge. They ask questions that are still burning today: Who am I really? What is constant in a world of change? What does freedom mean internally, existentially? In this work, Swami Kalki Kala , a Hindu monk in the Advaita Vedānta tradition, and Kali Jyoti Vosen , an experienced yoga teacher and trainer at Yogaleela , make these questions accessible and tangible especially for people who teach yoga. Because many feel that it takes more than technique and form. It takes depth. Presence. Clarity. This book invites you not only to understand the major themes of the Upanishads Ātman , Brahman , Māyā , knowledge , death , truth but also to bring them to life in your practice and teaching . It is about a yoga that not only moves, but also touches. What you can expect: Part I : Introduction to the origins, culture and thinking of the Vedic world and how the Upanishads emerged from it Part II : In-depth examination of the central concepts and teachings historically contextualised, clearly explained, practically relevant Part III : Concrete ideas for your teaching how to open up a tangible depth with space, language, presence and questions Bonus I : Seven carefully developed yoga flows , each embodying a central theme with introduction, sequence structure and breath focus Bonus II : Appropriate mantras for each flow , with meaning, application and connection to the teaching context This book is for yoga teachers, trainers and seekers who want to not only ‘teach’ yoga, but embody it. You don't need any prior knowledge of Sanskrit or philosophy just the openness to let the depth that is already within you take effect. Not a recipe book. Not a dogma. Not a new method. But an invitation to remember: Who you are. And what works through you when you do less and are more.
