The best thing a concerned American can do, is to send money to a reputable aid organization that is working in Nepal. My favorite would be the American Nepal Medical Foundation.
I was talking with my daughter in Rockville Maryland and she asked for some prayer flags. sure, why not?
You see prayer flags everywhere in Nepal. On each flag is a prayer, and when the wind blows, it reads the message and sends it to the universe. Boudhanath, the iconic temple of Kathmandu, is breathtaking for many reasons, but among them the colorful flags of Buddhist belief system.
Then we both had the idea: why not ask every concerned American to put up some prayer flags as a gesture of solidarity and support?
The earthquake aftermath is still in the acute phase. Nepal has the attention of the world, but it is inevitable that the gaze of world media will move to the next crisis, at some future point. When that happens, the people of Nepal will still be there. Recovery from an earthquake of this magnitude is going to take decades of work.
For that reason, I think putting up prayer flags will help.
PS – about me – I am an American RN who has been coming to Nepal since 2007 and I teach critical care skills to nurses and doctors here. I have written two books about health care in Nepal, take a look.
