Prem has a few different strategies for that type of situation if you ever find yourself in one again and need a little "satsang BS":

1-give yourself an imposing title first, before addressing the crowd, like "the living perfect______". Just fill in the blank, depending on the situation. No one will dare question you about your credentials with a vague, yet powerful title like that.

2-It doesn't hurt to get into a little "historical revisionism". For instance, you could preface everything with "many perfect____'s" have come before, but none really got the job done....while they're chewing on that one, just give your presentation, wait for some applause, wave your hands and exit stage...   3-say something inane, pause for a long time to look profound, then move on. Keep it general and banal. so banal in fact, that the audience will feel that they must have missed something profound, because what you just said is so simple and stupid, and they'll blame themselves for the misunderstanding....keep 'em guessing, it works every time...

4-threaten them with vague references, like "if you don't believe me and stop the practice of _____(your choice here), your mind will be like a truck full of rotting vegetables in the mid day sun.....or you'll shatter into a thousand pieces....

5-about 3/4 of the way through your discourse, you could thunder at the audience "who are you to question_______"(once again, your choice). Warning-you might want to practice this one a few times in the mirror or in front of some friends to make sure you have the right intonation etc.Not everyone can pull that one off right away....better get a little practice in first...

In summary, prem rawat has given us a rich reservoir of tricks that might help you out sometime, if you have the need to BS anyone....I'm sure other exes have a few they could recommend as well...

6-BONUS-You could have your partner come out and kiss your feet and put a crown on your head, while you wave your hands and flail around on stage. I would caution you to get a little practice in first before attempting this one...it could backfire if not done correctly with the right stage hands, lighting, music etc...
