Correct. You don't even have to be on the LHP (eastern or western) to realize your Greater Self, we realize this Self throughout our lifetime, what we do with these epiphanies is what places you on the WLHP or not.
I chose the example of Ceremonial Magic to respond to @Longfellow's question whether the practices were the same between (W)LHP and RHP.
Just as we cannot experience someone else's consciousness, we don't seem to be able to experience someone else's Greater Self either. It's an individual subjective experience. However, we can relate that experience to one another and compare it.
The Western Left Hand Path has many organizations and many adherents. Some of us work together in these organizations.
I am one of the instructors of the Sect of the Horned God and run their Order of Iblis, I've been a member of the Temple of Set and Ordo Luciferi, and ran my own organization for 8 years.
The LHP is quite diversified so there is a lot going on in different groups. Some have rituals and ceremonies, simple get-togethers, retreats, celebrations, etc. We all work together just like any organization would work together.
All the instructors are friendly with one another, we don't necessarily discuss our specific agenda in the Order that we oversee.Do you like talking to other instructors sometimes, about the path and guiding people in it? If it isn’t revealing too much, what would be some issues that you might discuss?
