We are all drawn to fire, entranced by its beauty and ferociousness. Its brilliance draws us in like moths to a candle flame. Thus, many of the celebrations that humans have involve lighting fires. They can be big or small; there could be many little lights or one giant inferno; they may float on water, burn on land, or rise high into the skies. Loi Krathong is a festival that is held each year in Thailand and a number of other places. During this festival thousands of little fires are lighted, presenting a marvelous sight for all the onlookers. It is believed that this tradition is an adaptation of Brahmanical festival, which was adopted by Thai Buddhists to honor Buddha.
