You may have heard people talking about "mindfulness". It's a big pop culture thing now -- I recently got some junk mail for a magazine about mindfulness. And it's big business, people are making money teaching corporate executives to pay attention to what they're doing, moment by moment.
The Pali word that gets translated as "mindfulness" is "sati"; in Sanskrit, it's "smrti". When Buddhism came to China they wrote it as 念, "nian"; in Japanese it's pronounced "nen". That kanji is composed of two pieces; the top half is "now", the bottom is "heart" or "heart-mind".
