My mother used to light this lamp on the last Saturday of Purattaasi month and I follow her tradition.
Carefully fashion it into a round bowl shape with a small crater in the middle to hold the ghee for the lamp. Transfer to a silver plate lined with a banana leaf. Mark the lamp with turmeric powder and kumkumam and add the remaining ghee into the centre of the flour lamp. Put a clean cotton wick and light it along an offering of betel leaves, areca nuts, coconut, fruits and flowers to the Lord. The lamp will be lit for at least a few hours and once all the ghee has been used up, remove carefully to another bowl. Remove the burnt wick and add the grated coconut, mix well and enjoy. Since raw coconut has been added, you will have to store in the fridge. If you don’t add coconut, it can stay out for 4-5 days.
