Re Funny you should mention that. On my TTC when MMY came to make us teachers he also gave out advanced techniques. On the flight back home folks were running around asking "do you remember the mantra that MMY gave you for an advanced technique?" A number of people could not or were confused as to it's pronunciation (including myself).
Ha-ha! There are also stories of people (here on FFL) who reverted back to their original bija mantras because they found the advanced technique mantra didn't agree with them. (I bet there was no money-back-if-not-completely-satisfied clause.)
