The Archons interfere by putting every possible distraction between the person and their actual work. The person loses the ability to follow instructions, omits things, changes the content they are given, or will even start manifesting physical or mental fatigue or illness when applying themselves.

When this happens, the only thing that appears to help is the direct assistance of their tutor. By writing notes for every session they do and sharing them with the instructor, the guide is able to help them navigate every step of the way, and identify what is being done to them.

Then it becomes a test of endurance, which a committed student will win. Without a guide, they lose. Its as simple as that. I believe this is why the mysteries were taught hand to hand, mouth to ear, over the centuries: to ensure the best chances that the Archons would be overcome.

With a qualified tutor, even a student of very average ability and no special gifts or talents will succeed with Initiation if they are truly committed, and trust their instructor. However, even a gifted student of high intelligence and ability will fail without one. In fact, it seems the most 'intelligent' types fail the fastest.
