Some call it a Mahavidya - the greatest knowledge, and there are just ten of those, with this the first one, while others would call it forbidden knowledge, because it is that powerful as it changes one's perspective of reality. Most would not believe it still exists, but in the corners of the world that no one wants you to know about, practitioners achieve everything that they ever wanted, and such is the power of the Kali Tantra. It is pure magic, and this conversation between the Gods - Shiva and Parvati in their Bhairava and Bhairavi form detail every single bit of the practice. This book has kept it pronounceable according to the origin, and explained it to make it understandable for those indulged in the practice, and even for those who are just dabbling to explore it.
