Describing the nature of the universal divine energy of Kundalini and its relationship to spiritual growth, Shri Dhyanyogi Madhusudandasji, a great saint of India and a master of Kundalini Maha yoga, explains how to awaken this dormant energy in spiritual aspirants. In this new edition, Shri Dhyanyogiji shares his energy, wisdom, and technical knowledge of this sacred tradition, making it accessible to both the beginning and the more advanced student of yoga. Featuring helpful charts and diagrams of the chakra system and the 18 major nadis, questions and answers about meditation and the spiritual path, as well as encouraging experiences from students, this guide brings together knowledge that had been formerly unknown outside of this yogic lineage.
