"During the day, children go from door to door singing folk songs in praise of Dulha Bhatti. These children are given sweets and savories, and occasionally, money. Turning them back empty-handed is regarded inauspicious.
The collections gathered by the children are known as Lohri and consist of til, gachchak, crystal sugar, gur (jaggery), moongphali (peanuts) and phuliya or popcorn. Lohri is then distributed at night during the festival. Till, peanuts, popcorn and other food items are also thrown into the fire."
I find it quite fascinating that that different cultures around the world celebrate the same astronomical event, i.e. Winter Solstice in different, yet similar ways.
