The Ubon Ratchathani Candle Festival, the most elaborate of the traditional parading of candles to wats is held in Ubon Ratchathani, Isan, Thailand, around the days of Asanha Puja (which commemorates the Buddha's first sermon) and Wan Kao Pansa (which marks the beginning of vassa).
“Khao Phansa”, the Buddhist Lent is a time devoted to study and meditation. Buddhist monks remain within the temple grounds and do not venture out for a period of three months.
In the past, still have no electricity.
We use a candle in reading study Buddhism.
The light that is like the light of wisdom.
