HARI OM SAI RAM ,
General Message for all:
If one is following Navratra and wants to keep Akhand Jyoti, do Kalash Sthapna and Khetri Beejna and properly follow all other important rituals of Navratra, then:
1. In Water Kalash please put 1 choti elachi, 1 clove, 1 piece sabut haldi, 1 coin, 1 Sabit Supari, little rice, 1 coconut, 7 mango leaves and little Jau. (You may even put little more quantity of  all things, in odd numbers)
2. You may do jal prawaha of old Kalash and keep new  Kalash every year. It is ideal to do this every Navratra (total 4 Navratras in a year).
