This book is a brainchild of the explorers while making the website "demystifyingkundalini.com" The website creator began to suspect that if the website went bad due to any reason unfortunately, then all the hard work would be spoiled, and all the text written would be gone. In addition, the website creator also desired that the website should be available on any e-reader, so that the readers are comfortable in reading, and the eyes are not affected. Both these objectives could be fulfilled only by creating an e-book of the website. Hence fixed web pages and some web posts which were not included in the another e-book were included in this e-book. In another e-book, all the web posts related to Kundalini were inserted, which contained all the remaining material. The name of that other book is "Kundalini science- A Spiritual Psychology". The first two home pages of this website have been included in still another book, "kundalini demystified- what Premyogi vajra says". The description of Tantra and Kundalini is clear, simple, true, natural, practical and scientific as described by Premayogi Vajra. Such description is not visible anywhere else. Hope that dear reader will take full advantage of the book presented. Premayogi Vajra was born in the year 1975 in a small village in the beautiful basket valley of Himachal Pradesh, India. He is naturally fond of writing, philosophy, spirituality, yoga, public service, applied science and tourism. He has also done commendable work in the field of animal husbandry and veterinary medicine. He is also fond of polyhouse farming, organic farming, scientific and water conserving irrigation, rainwater harvesting, kitchen gardening, cow farming, vermicomposting, website development, self-publishing, music (especially flute playing) and singing. He has also written close to ten books on almost all these subjects, whose descriptions are available on Amazone Author Central, Author Page, Premyogi vajra. The description of these books is also available on his personal website demystifyingkundalini.com. He had also been a Vedic priest for a short period of time, when he performed religious rituals in people's homes with the help of his Vedic priestly grandfather. He has gained some advanced spiritual experiences (enlightenment and Kundalini awakening). His autobiography, along with his unique experiences, is particularly shared in the book "Physiology Philosophy - A Modern Kundalini Tantra (A Yogi's Love Story)" written in Hindi. The matching equivalent of this book in English is "Love story of a Yogi- what Patanjali says". This book is the most prominent and ambitious book of his life. This book contains the most important 25 years of his life's philosophy. He has worked very hard for this book. In a quality and unbiased review on Amazon.com, this book has been reviewed as a five-star, best, must-read and excellent book. Google Play Book Review also found five stars for this book, and this book was rated as good (cool). Premyogi vajra is a mysterious person. He is like a polymorphic man, who has no fixed form of his own. His actual form depends on the size and type of the trance/Samadhi that he is continuously experiencing in his mind, no matter what he looks like from outside. He is enlightened (self realized), and his Kundalini has also awakened. He had self realization or enlightenment naturally / through love yoga, and Kundalini awakening through artificial means / Kundalini yoga. At the time of natural samadhi, he was assisted by symbolic and uni-vehicular Tantra yoga, while at the time of artificial trance/Samadhi he got the help of complete and bi-vehicular Tantra yoga along with the majority of his own efforts.
