If you wish to awaken all the energy centres I really recommend getting the book Kundalini Tantra by Swami Satyananda Saraswati... It contains techniques to awaken all energy centres as well as how to awaken the kundalini force... As far as I have tested they have been very powerful techniques... (Whenever a centre has awakened my consciousness has been overflooded with euphoria so intense that I almost burst )...

It requires daily practice to achieve great effects.. The effects are of a divine-like quality...
