The day ends by getting rid of him.
After dark the effigy is pulled down off its tripod. In many toles a man of the Pode community — traditionally the valley's sweepers, and so the people who carry away what nobody else will touch — takes the role of the demon or drags the figure out of the neighbourhood, running ahead of it with the tole shouting after him. The figure is hauled to the nearest river or to the edge of the settlement and burned there, and the evil accumulated over the year is understood to go up with it.
The caste logic of who does this is not incidental and is not softened by anyone who keeps the festival. The work of removing pollution is assigned to the community historically assigned all such work, and the ritual states that assignment out loud once a year.
After the burning the festival season is open: Gai Jatra, Janai Purnima and Indra Jatra follow over the coming weeks, and the Buddhist holy month of Gunla begins two days later. The house has been cleaned, the demon is ash, and the year can properly start.
If you want to see this, be in a Newar neighbourhood at dusk and follow the noise. It moves fast and it does not wait.
