In the middle of my morning session I suddenly realized that I was no longer repeating I AM and instead, some time prior, had unconsciously shifted to a different mantra - TROUBLE (pronounced in two syllables like truh-bool). Of course my first though was, what's the meaning of this? After entertaining the question for about five seconds I followed the perennial Yogani instruction of disregarding the scenery and gently favoring I AM. The problem was, I AM no longer had any traction. It was as if bliss consciousness had expelled I AM and was demanding something different. Eventually I stopped fighting and just let TROUBLE be the mantra. Almost immediately I drifted back in to bliss consciousness and the meditation proceeded entirely uneventfully for the rest of the session.
I've experimented with different mantras in the past but it was always on the level of the conscious mind. This was different. This happened while deep in meditation. I have no recollection of when it started or how I got their. I only realized it had happened sometime after the fact.
Anyway I'm not too concerned about it except for some curiosity as to whether anyone else had experienced something similar or if anyone has any specific knowledge of the word TROUBLE as a mantra.
