I spent about three days at Wat Pha Nanachat (วัดป่านานาชาติ), the international forest monastery in Ubon Ratchatani several months ago and it was quite the experience, though difficult to maintain coming from a world of distraction.  This monastery, or wat, was the fruit of Ajan Cha, an eminent monk of the Thai forest tradition.  The hardest part about staying there was sitting on the ground all the time with legs made of tin.
