Winter in Bhutan is the time for festivals. Many of the leading dzongs (fortresses, now administrative hubs) and monasteries hold the annual Tshechu festival at this time of the year. Cham or mask dance is a part of the Tshechu festivals. These colourful and energetic dance programmes are considered to provide protection from misfortune and exorcise evil influences. At many places, a thongdrol (which means 'liberation on sight,') &ndash usually a large thangka or scroll &ndash is revealed to confer blessings on those assembled. The Tshechu and other festivals are also seen as an occasion for families and friends to come together people walk long distances to attend the festivals. Hence, arrive early at the dzong or monastery to secure a vantage point, especially if you are a photographer.
