Hi Lucas,
I think we could exchange a lot of opinions about the Goenka technique. But what does it help? It would help only if we could find any progress towards Nibbana. That is what I can not confirm.
When I started on Lals website I easily made progress and the satara iddhipada were at work all the time. Even today I read “old” posts and find new details I did not grasp before. Every day I think about the Dhamma and that is real bhavana as per the Buddhas teaching. Here is panna to be gained, which is needed to attain Nibbana. That’s all what I want. I can confirm to have reached a high level of niramisa sukha or nivana which is such a relief. This comes from real understanding and does not require much effort (at least not for me). Also this niramisa sukha does not go away, whether I sit every day for meditation or not. That is because real grasping of the unfruitful and dangerous nature of this world is forever. If you feel you can attain something with the Goenka technique, just do it.
