Excellent Treatise on the Kundalini Awakening
The Serpent Power by Sir John Woodroffe offers what is perhaps the best original written work in English on the topic of Kundalini Shakti. Also known as the “Serpent Power”, Shree Mahakundalini Shakti is the very power of spiritual transformation and physical rejuvenation. She is the fire of yoga to the yogis, the power of right knowledge to the jnanis and energy of samadhi to the meditators.
