In the ritual, people bring sweets of their choice and burn
diya over it by putting a cotton wick soaked in ghee. The sweet and the diya are
held below any clean iron metal vessel or instrument.
The diya deposits black substance on the iron metal vessel
and that's used as kajal – eyeliner.
Another important ritual that is observed on Thursday in
Margashirsh month in Maharashtra is the
Margashirsh Lakshmi Puja.
A Nag Puja is also held on the day.
