By happy coincidence - though Buddhists will tell you that there's no much thing as coincidence - I ended up in Chiang Mai during the Loi Krathong and Yi Peng festivals (the latter overlaps with the former). I released a small float ornamented with orchids, incense, and a candle, into the Ping river in the spirit of Loi Krathong. Then, watched hundreds of floating lanterns be released into the sky.
Chiang Mai, Thailand November 2015
It was the most beautiful thing I've ever seen.
