Glenn was one of the good guys for sure and the man who set me on the path some years back. Like many others I miss him and his work and ways had a great impact on my life.
What I liked most about him was his no BS style, he once called his methodology the McDonald's of enlightenment. Wish he had said Burger King, as their burgers are better but there we go. The chapter in Path Notes about him masturbating is pretty refreshing in this line of literature! His other works Shadow Strategies and Martial Arts Madness are worth a read also.
He created his own system, Hoshin Jutsu, which is full of interesting stuff. Always a student, he cherry picked the best part of many other traditions, took out the crap and presented a martial art/esoteric system that he worked to perfect. Hoshin offered a well rounded approach including effective martial arts - largely based on taijutsu - energy work, an academic corriculum covering all manner of texts from strategy, philosophy, energy work, shamanism, leadership etc. In addition, a core element of his teaching was Kundalini. He presented an empirically tested system of arousal and personally lead 100's of individuals through the process - I aint one of them. He emphasised the pitfulls of a potentially dangerous process so one could mitigate them as much as possible. He really just wanted us all to be better human beings and have a laugh while doing it - and for it not to take 30 years to get somewhere.
The Hoshin (www.hoshin.com) are a fun bunch of people, who have high level of expertise from a number of different systems. Over in North America there are a number of quality individuals running workshops, training camps including Mark Lawrence in Canada, Bill Trumper and Ian Cox. Over in the UK Susan Williams runs the Hoshins Meditation Mastery and Esoteric Energy Courses. These cover the Kundalini Arousal process and then move on to other interesting areas.
Glenn worked with lots and lots of different people from all walks of life and his work is not confined just to Hoshin. He talked highly of the Uma Tantra guys - and they new him way better than I did. I know they are honouring him and his work and building upon it. He never wanted stuff to be static, evolution in all things!
Anyway thats my 2 pennis worth.
