Ebook: Tantric Techniques: Awakening the Power of Kundalini & Chakras, Kundalini Awakening

If you want to learn about Kundalini in any kind of organized way, your choices are limited. This is one of the only books I could find which offer any kind of useful information. which is incredibly dense, uses pretty esoteric Sanskrit words very liberally and without much explanation, but is nonetheless fairly well organized, detailed and fascinating. However, if you want to learn how to integrate Kundalini practice into your life, I'd probably start here.

A well written Yogic text with instruction and explanation about chakra activation and Kundalini rising. Everything you need to know to start a serious practice.
