As I grew up, things were different. Amma wanted me and my sister to learn all these customs. On the 8th day, Ayudha Poojai or Saraswathi Poojai was performed. Generally my duty was to clean all pictures, clean the poojai room and other household items.
On this day, we put our books in front of the image of Saraswathi to seek her blessings for success in our studies. Typically the whole house was cleaned, cars and bikes were washed and then a small Poojai was done. Sundal and Payasam were served~Find recipe for Sprouted Red Bean Sundal here.
It is on this day, all cars, busses, bikes, and even homes are washed completely and then decorated grandly, with yellow sandal splash or Pottu/Tikkas and kungumam/kumkum as these are good luck symbols. The purpose of this worship is to pay homage to all implements that help us in everyday life.
Vehicles cleaned and decorated for the Poojai.
May this Navrathri bring joy, health and wealth to all!
