Dussehra is a major Hindu festival celebrated in India at the end of Navaratri each year and there alot of mythology to it which can be read by going to the wikipedia page. It is mainly a victory of good over evil.
I had vistited Ladakh during the month of February of this year. This was my fifth trip to Ladakh and my first time to visit Ladakh in the winter months. Ladakh in winters can be very cold. It is also during this time that the Dosmoche festival is celebrated. This is a two day festival and is celebrated at Leh, Likir and Diskit monasteries. However I only observed the festival at Leh monastery during the first half of day one.
