MINDFUL & THOUGHTFUL
13. Now there the Blessed One addressed the brethren, and said: ‘Let a brother, O mendicants, be mindful and thoughtful; this is our instruction to you.’
14. ‘And how does a brother become mindful?’
‘Herein, O mendicants, let a brother, as he dwells in the body, so regard the body that he, being strenuous, thoughtful, and mindful, may, whilst in the world, overcome the grief which arises from bodily craving–while subject to sensations, let him continue so to regard the sensations that he, being strenuous, thoughtful, and mindful, may, whilst in the world, overcome the grief arising from the craving–which follows our sensation-and so also
as he thinks or reasons or feels let him overcome the grief which arises from the craving due to ideas, or reasoning, or feeling.’
15. ‘And how does a brother become thoughtful?’
‘He acts, O mendicants, in full presence of mind whatever he may do, in coming out and coming in, in looking and watching, in bending in his arm or stretching it forth, in wearing his robes or carrying his bowl, in eating and drinking, in consuming or tasting, in walking or standing or sitting, in sleeping or waking, in talking and in being silent.
‘Thus let a brother, O mendicants, be mindful and thoughtful; this is our instruction to you.’
