Relationship between sampajanna definitions in SN 47.2 and SN 47.35 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.
In line with what I said in my other answer, both are descriptions of self-awareness, of not getting carried away by the circumstances.

This does not refer to "zombie bare awareness" executed mechanically, but to normal, pragmatic, careful self-awareness of an intelligent person.
