Emergence is directly knowing the Noble Way!
At the stream-entry moment - right there & then - as an internal light flash:
Right view emerges from wrong view and from all defilements as seeing...
Right motivation emerges from wrong motivation as now directing...
Right speech emerges from wrong speech as kindly embracing...
Right action emerges from wrong action as clever originating...
Right livelihood emerges from wrong livelihood as full cleansing...
Right effort emerges from wrong effort as enthusiastic exerting...
Right awareness emerges from wrong awareness as alert establishing...
Right concentration emerges from wrong concentration as non-distraction...
Externally this change-of-lineage emerges from all symbols and conventions!
This mental remodelling is an irreversible phase transition to the Noble state!
Vism 681

Noble Emergence from all the assuming mental fermentations!
