"Monks, without directly knowing and fully understanding visible forms, without becoming dispassionate towards them and abandoning them, one is incapable of eliminating suffering.
Sounds ...
odours ...
flavours ...
tangible objects ...
Without directly knowing and fully understanding mind-objects, without becoming dispassionate towards them and abandoning them, one is incapable of eliminating suffering.
But, monks, by directly knowing and fully understanding visible forms, by becoming dispassionate towards them and abandoning them, one is capable of eliminating suffering.
Sounds ...
odours ...
flavours ...
tangible objects ...
By directly knowing and fully understanding mind-objects, by becoming dispassionate towards them and abandoning them, one is capable of eliminating suffering."
