It's important to note that the sales line of this being purely practical without dogma is completely false. Goenka is very clear in the lectures that meditation is all about purifying yourself for reincarnation. There's tons of anti science stuff, like claiming Buddha knew more about physics than the inventor of the cloud chamber.

The entire time, he chants in a dead language, and they want you to blindly recite things in said dead language. He purposely plays with his accent and speaking in order to push a bit of mystical properties to what he's saying (repeating words over and over, laying on a thick accent, whereas at other times he is capable of speaking very clearly).

The actual practise may be fine, but I found the woo-factor to be incredibly high - false advertising.
