On the 8th day day of Durga pooja/Navratri, we have to perform special poojas throughout the day for Devi Durga. The usual practice is to perform 4 poojas on this day, one each during sunrise, noon,sunset and at night.
In the morning, the devotee should get up before sunrise and finish bath. It is advisable to prepare some form of simple dish or delicacy to use during pooja for Durga devi. [ One simple dish is a mixture of honey, raisins and bananas].
Place the dish in a small utensil in front of the idol of Durga devi. Now sit in front of Durga devi together with your family, and invoke Lord Ganesha with the following sloka. Hold a flower in your right hand above the utensil while chanting the sloka. Chant the sloka 3 times and then place the flower on the books.
