I perfectly understand what you say, but I never mentioned Breath meditation as the tool for liberation. That is only one of the three legs of the tripod: Sila, Samadhi, Panna.
“sukha vedana” are good or pleasurable body sensations. That is an unusual feeling. Most of the time your body is full of gross and heavy vedanas.
Goenka’s body scan technique is about experiencing anicca with the body sensations (coming from all angles mentioned before), with the consequence realization of dukha and anatta; Complete Tilakkhana.
I would like to understand why you keep asociating along the comments that breath meditation is the Goeka’s technique.
I’m not a defender of this method, that’s why I’m here. Your explanations about the suttas and the abhidhamma are very consistent. I only want to get a better understanding of meditation
