There has been a request for dates to be listed. I have started adding that in the notes section of the gurus.
There are many ancient masters of this path not listed. The primary focus of this lineage chart is to help those actively seeking a guru/system/path. A number of the ancient masters were acknowledged by Pravesh K. Singh in a post of his.
W.C. Vetsch is a superman when it comes to melding Eastern and Western viewpoints on Sant Mat and related fields such as conspiracy theory, hard logic, high magick, math, gnosticism and fringe science. His Essentials of Mysticism is a master work. He's the only person whose grasp of the inner and outer is strong enough to remind me of Maximilian Sandor (aka Joachim Steingrubner).
Spiritual Freedom Satsang is where I get my email on. Here you will find Michael Turner, the hippest hippie Sant Mat guru on Planet Earth. Who else is pro-marijuana and meat-eating in the Sant Mat community? Dont blood-test me (grin). Sant Santati is also an excellent group with very uptone participants. And of course Radhasoami Studies is great because it is unmoderated free-for-all action!
Sound Current Rider is a site crafted with vision. This site was made from a mental blueprint. Not randomly thrown together. The only problem is, it's such a nice site, you want to quit looking at it and return to the inner (grin).
