There are many images that could compete for a “2011 photo of the year” award in China. But few would have bet that the picture of an unknown monk praying over a dead man would turn out to be among the most popular.
Memorise a sutra or mantra today! When you meet someone who is down or in fear, a gentle recitation can go a long way to help.
As always, common sense apply. If the person need some water or food, give water and food for the body, and offer a prayer for the mind and heart.
