Gunlā is the tenth month in the Nepal Sambatlunar calendar, the national lunar calendar of Nepal. It corresponds to August of the Gregorian Calendar. Gunla is a holy month for Newar Buddhists when they recite the scriptures, observe fasts and visit places of worship playing devotional music. It is one of the most important events in Newar Buddhism. The practice of observing the sacred month is descended from the rains retreat dating from the Buddha's time when monks stayed in one place and taught the Dharma. According to traditional beliefs, during primitive times, too much rain would fall. Due to this rain, the mud houses during the time would get devastated, moreover floods and landslides would add melancholy in people's lives. So, in order to downturn the melancholy, and be safe from floods and landslides, people would go toSwayambhu playing the devotional music as it was in an elevation.
