Buy this book, read it carefully, reflect on what you find, assimililte what you can, then move on and don't look back!
There is much about Tantra and Hinduism and it's nature that is valuable in this book. You need to know it and what this "thread" of Tantra is about.
For the web of life is created by many such threads.
Look for yourself on page 26 table 5 to understand the true nature of this Tantra: The Ten Karmas of Mantras!
Look and see for yourself what this path is about: This is a path of power, manipulation and desire.
Only the peaceful mantras of Shanti Karma do not bind you to the invisible "thread" of the dark side of Tantra.
As University graduate in Comparitive Religion and India studies, an ex-personal student of Mr. Johari in the 70s, and as a person who has lived and traveled in the Far East for the last 8 years studying Hinduism and Buddhism, take my advice and do not be led into any New Age dreams or fantasies about the real nature of this type of Tantra.
If you are attracted by the beautiful sensual art of this book and enter into the "Door" where they stand guard and beckon so seductively, know that in this house of Beauty and Music and art Philosophy and Laughter lives deep within the basement a terror of dark magic power far beyond your comprehension:
Dhumavati - She who stalks the burning ground, She who haunts the crematoriums. She who waits in dark places unkown and long forgotten to most living men to caputure unsuspecting souls.
She who is distorted and disbalanced. She who's Yantras and Mantras cause pain, suffering, death and despair. She who does not fear Shiva.
This is part of the Tantra that is contained in this book. Do not think it is myth or old wives tales. It is as real as the primal sounds and patterns that this book contains.
Tread this path as carefully as you would when walking a razor's edge. Do not think it is fantasy, it is indeed a dark reality few can fathom. If you, as a neophite tantrik, think you can cope with the dark forces unleased by the Uchchatan, Vidweshan and Maran Mantras that you may desire to invoke, you are totally deluding yourself.
Beware - amid the images that entice so gently and blissfully also live the the dark side of Tantra and power of Kali ma, Chinnamasta and Dhumavati. When you open this book and when you close it Circle yourself with the protection of the Maha mantra: Om Shanti - Sita Ram, Ram Ram, Hari Ram, Om Shanti Shanti Shanti. Read this book! And take care. Good luck my friends. Om Shanti Shanti Shanti.
