Sri Kundalini-Shakti — Serpent Power

This book presents the Shaktist philosophy, a system of symbolism, and yogic practices used in some lines of Advaita Vedanta.
We tend to associate Shaktism — particularly Kundalini-Shakti, chakras, and nadis — with Tantra, Nathas, Hatha Yoga, and other relatively late... trends in Hinduism, but as the author of this book convincingly shows, both Shaktism in general and the concept of Kundalini-Shakti, and even the yogic practices for its awakening, are already represented in the Vedas and their philosophical applications — the Upanishads and Aranyakas. In particular, Shaktism in Advaita Vedanta is by no means limited to Saundarya-Lahari of Shankara.
This book claims to describe this ancient Vedic system, including various yogic techniques — asanas, bandhas, mudras, pranayamas, and finally, meditation.
In confirmation of his words, the author cites numerous sources, primarily the Upanishads and the writings of Shankaracharya.
