[443] And how does a bhikkhu dwell contemplating feelings (vedanā) in feelings both internally and externally?
Here a bhikkhu understands a pleasant feeling (sukhā vedanā): 'It is a pleasant feeling'; he understands a painful feeling (dukkhā vedanā): 'It is a painful feeling'; he understands a neither-painful-nor-pleasant feeling (adukkhamasukhā vedanā): 'It is a neither-painful-nor-pleasant feeling'; he understands a worldly (sāmisā) pleasant feeling: 'It is a worldly pleasant feeling'; he understands an unworldly (nirāmisā) pleasant feeling: 'It is an unworldly pleasant feeling'; he understands a worldly painful feeling: 'It is a worldly painful feeling'; he understands an unworldly painful feeling: 'It is an unworldly painful feeling'; he understands a worldly neither-painful-nor-pleasant feeling: 'It is a worldly neither-painful-nor-pleasant feeling'; he understands an unworldly neither-painful-nor-pleasant feeling: 'It is an unworldly neither-painful-nor-pleasant feeling.'
Thus a bhikkhu dwells contemplating feelings in feelings both internally and externally, ardent, clearly comprehending, mindful, having removed covetousness and grief regarding the world.
