In Japanese, this word means innocent, or one with no knowledge of good and evil. It literally means "without mind".
We haven't had a chance to fully research this word since this was a special request for a customer. It apparently has a good meaning in conjunction with Chan / Zen Buddhism in Japan. However, out of that context, it means mindlessness or absent-minded. To non-Buddhists in China, this is associated with doing something without thinking.
