The most sacred  part of this unique festival is lighting of oil lamps at homes, temples and  in  the workplace. The idea behind this festival is to  get rid of the old, unwanted things in the house and replacing them with new ones and it has philosophical connotation, implying elimination of bad or negative thoughts, ignorance  and replacing them with positive  thoughts,  just like a ray of light dispelling darkness.  Hence in this festival, oil lamps are personification of holiness, welfare  and prosperity.  The place where it is lit, gets sanctified, creating positive energy. When you light up a series  of oil lamps at home, it brings in happiness, so much so, in the temples oil lamps create an atmosphere of reverence, respect  and devotion to all-pervading gods.

 During the festival  days, around the four  Maada streets, each day there will be a procession of  deities (Uchavars). The car (chariot / Ther) festival falls on the 7 th day and deities would be taken out on five  colorfully decorated  huge wooden chariots  pulled manually along the  four Maada streets.
