At one occasion the exalted one dwells at Ambapāli's Grove at Vesāli. OK there the exalted one addressed the almsmen:
'Almsmen'
Those almsmen replied to the exalted one:
'Venerable Sir'
The exalted one said this:
'Meditative, almsmen, aware, an almsman should dwell. This is our instruction to you.
And how, almsmen, is an almsman meditative?
Here, almsmen, an almsman looking into body dwells in body as the ardent aware meditator would be disciplining the avarice and distress about the world; looking into feelings dwells in feelings as the ardent aware meditator would be disciplining the avarice and distress about the world; looking into mind dwells in mind as the ardent aware meditator would be disciplining the avarice and distress about the world; looking into principles dwells in principles as the ardent aware meditator would be disciplining the avarice and distress about the world. OK so, almsmen, is an almsman meditative.
And how, almsmen, is an almsman aware?
Here, almsmen, an almsman when walking to and fro, he is doing it aware; when watching over, watching around, he is doing it aware; when stretching, bending, he is doing it aware; when carrying an overlay plus bowl plus robe, he is doing it aware; when eating, drinking, consuming, tasting, he is doing it aware; when defecating and urinating, he is doing it aware; when going, standing, sitting, sleeping, wakening, talking, being silent, he is doing it aware. OK so, almsmen, is an almsman doing it aware.
Meditative, almsmen, aware an almsman should dwell. This is our instruction to you.'
