Ah, is it this one?http://www.ajahnchah.org/book/On_Meditation1.php#foot677
Whatever we do we take care. A sense of shame4 will arise. We will feel ashamed about the things we do which aren't correct. As shame increases, our collectedness will increase as well. When collectedness increases, heedlessness will disappear. Even if we don't sit in meditation, these factors will be present in the mind.
The footnote is
This is a shame based on knowledge of cause and effect, rather than emotional guilt.
The footnote is probably by the translator, but I think it means something like a wholesome sense of shame or conscience (hiri
in Pali) which we can use to protect ourselves. We develop a sense of what consequences our actions will have when we are in the collected state, and thus we restrain ourselves from doing wrong. As it is based on consequences, it is "based on cause and effect". This is contrasted with the idea of "emotional guilt" - just beating ourselves up for things we did in the past - which is fruitless.
Bhikkhu Bodhi has written a nice little article on hiri
and its counterpart, ottappahttp://www.accesstoinsight.org/lib/authors/bodhi/bps-essay_23.html
