A bit of clarification: I was an Adept withing the ToS for just about 4 years. A number of priests in the temple felt I should move in that direction, and it was then that I began the process that eventually led to my resignation. I began to recognize that the temple is not a school of initiation but a religion. If anyone doubts this please note that any criticism of the temple is usually met with a personal attack and heated defense my some member of the priesthood. Now, it has been quite a few years since my college days but I have no experience of an actual school that maintains a priesthood. If the temple is not a religion then why a priesthood? It can be denied, but at a certain level in the ToS this is an open reality. The priesthood knows this, why they continue to attempt to keep it secret I do not know. If you do not believe me then go do the research. As mentioned before, you can find the relevant inner temple documents online.
When I joined the temple there were no public writings and there was no internet (as it exists today). Luckily the people who are today developing an interest in this stuff have many resources of information at their finger tips. As pointed out earlier most, if not all, of relevant ToS info is available in one form or another online or at the local book shop.
Regarding mouth to ear: yes, a mentor is of great help. But I ask you, who was Aquino's setian mentor? Who was the setian mentor to the original founders of the temple system? My point is that it is possible to find true Initiation outside of the ToS. Is it easy? Not necessarily. But it is possible.
One of the greatest gifts I received from the temple was the contact with other individuals who were making magickal experiments. At the time, with no modern internet, this was extremely important. I imagine that today's new seeker can make relevant contact with potential mentors through forums like this, meetups, local magickal gatherings, organizations like the Rune Guild, and yes, the ToS.
I am not attempting to discourage people from exploring the temple. The temple serves many useful functions. I count amongst some of my closest friends current ToS members of grades through MT. However, I still maintain that the temple is a religious organization first and foremost. Those who are magicians or aspiring magicians can take it or leave it, membership in a religion is not at all necessary for evolving Initiation.
To Sireal: I am sorry that you feel the need to personally attack me. I recognize that your role, and identification as a priest requires you to do so.
To L. Keane: if the ToS continues to serve you well then by all means keep at it. I have read your public writings and you seem to be experiencing the magick of Initiation. Above all, do what works.
To the new folks seeking info about setian praxis: be scavengers...be diligent. You can find this information all around you. Your existence breaths it. No organization has copyright on Initiation. It cannot be given to you. True Initiation is internal.
