What is the relationship between the definitions of sampajañña (clear comprehension) in SN 47.2 and SN 47.35?
From SN 47.35 (translated by Bodhi):
“And how, bhikkhus, does a bhikkhu exercise clear comprehension? Here, bhikkhus, for a bhikkhu feelings are understood as they arise, understood as they remain present, understood as they pass away. Thoughts are understood as they arise, understood as they remain present, understood as they pass away. Perceptions are understood as they arise, understood as they remain present, understood as they pass away. It is in this way, bhikkhus, that a bhikkhu exercises clear comprehension.
From SN 47.2 (translated by Bodhi):
“And how, bhikkhus, does a bhikkhu exercise clear comprehension? Here, bhikkhus, a bhikkhu is one who acts with clear comprehension when going forward and returning; when looking ahead and looking aside; when drawing in and extending the limbs; when wearing his robes and carrying his outer robe and bowl; when eating, drinking, chewing his food, and tasting; when defecating and urinating; when walking, standing, sitting, falling asleep, waking up, speaking, and keeping silent. It is in such a way that a bhikkhu exercises clear comprehension.
