My suggestion would be to stop using Mr Goenka's technique and try simple calm-abiding meditation for a month. You will almost certainly notice significant differences.
Sure. And as he proceeds, he will reach the same wall that he reached now. 
Can you tell me more about this stefan? How precisely will he end up being so confused after practicing calm-abiding which is all encompassing without fabricating? Are you familiar with this practice? In calm-abiding there is no "searching" via "scanning" for sensations
this alone not to mention anapana at the nose is enough for an ego cluttered mind to create more confusion and strain 
...
I, like Matthew would warmly advice you to lay down gOENKA for a month or two and try and see for yourself if Calm-abiding is something for you or not? Listen not to what others have to say about it but test and see for your self.

Maybe you're right, and Gonka-style-Vipassana isn't the right thing for Martin. Maybe we both are wrong and he should try Yogananda-style-Kryayoga instead. There's so many things to advice, how should he judge? Should he try them out all? Randomly jumping from "good advice" to "good advice" every two months?
Dear Che, I would advise you to lay down your practice for two months and join the "Hare Krishna's" instead, who are a decent lot. Then - judge for yourself!! - please enter the "Scientology church" for some months, and after that join Bagwan. After all, how can you judge for yourself, if you don't try it? Where is this going to lead you? I know where this sort of thing led me ...
One thing I really like about Goenka is that he advises you to
stick to it. In EVERY practice (be it Vipassana or Guitar) comes the moment when you don't see the point of it any more, where you think it's no use to go on ect. THIS MOMENT IS A TEST. "Are you able to stick to it allthough it's a bit tricky right now?" You have to get past this point or no technique will help you. Because it's likely you'll drop any other technique as soon as you experience the wall of your own ego again.
How precisely will he end up being so confused after practicing calm-abiding which is all encompassing without fabricating? Are you familiar with this practice? In calm-abiding there is no ...
No, I'm not familiar with this practice, and I never would advise anyone to stop practicing it because he experiences mild difficulties. I'd advise him to carry on with his calm-abiding meditation.

Sorry Martin

unknowingly you entered the "Battle of the Techniques" ... sometimes it is like "The Life of Brian" ... but really it's up to you to decide your way. I advised you to stick to Goenka only as a counterweight to the advises to try something else.
We are all no teachers. It really isn't up to us to give you advice which path to choose.

Dear Che, I'd like to advise you (again!!) to lay down your calm-abiding for some weeks and try Goenka. Then you can judge for yourself wether THIS routine of scanning really is "searching for sensations" ... it isn't ...
And, the ego-cluttered mind doesn't create any confusion and strain due to Anapana ... no, the ego-cluttered mind is shown his own confusion and strain that has been there all the time again and again and again. three days of Anapana isn't exactly nice, but most beneficial to why I should stay and take it serious. I was taught a LOT about my mind and my ego in those three days of Anapana.
