In the modern era there are many books on the physical aspects of Yoga. This book complements physical yoga by presenting the deeper dimensions of Yoga. It includes insights into the paths of Reflection (Gyana), Love and Compassion (Bhakti), Awareness in Action (Karma), Circulation of Energy (Kriya) and the Yoga of Sound (Mantra Yoga) from a scientific, spiritual and practical perspective. Among other things, it describes aspects of the subtle body, such as the chakras and koshas. Practical indications are also given on the process of meditation. The book ends with Q & A sessions (known as satsang) on subjects such as the value of awareness and non-attachment in everyday life. This book can be a useful source book for those who are looking deeper on the path of Yoga.
