Mindfulness
http://www.tricycle.com/dharma_talk/3648-1.html: I found this article quite bogus. It is certainly possible to find beauty in impermanence, or even in a burning house (the beauty is in the caring for others who might be trapped, as well as in the fire itself). If mindfulness has any point at all, it's about caring more, not caring less.
To be fair, the article is mostly about beauty in the realm of sense perception (whereas I am using the word to point at other things), but even there I would emphasize that there is nothing particularly "lack[ing] of worth in mental and physical sensations" -- on a gross level, our mistake is in our attachments and aversions to these perceptions.
