Navratri is considered very important in Hindu religion and during this time 9 forms of Mata Rani are worshipped. A fast for 9 days is also observed during Navratri. This year Chaitra Navratri will start on 9th April and end with Navami on 17th April. But before installing the Kalash during Navratri, you must do some things so that Mata Rani can reside. Therefore, do this work before Navratri starts.
House cleaning:
According to religious beliefs, special care should be taken about cleanliness during Chaitra Navratri. -Clean the house thoroughly before Navratri starts. Keep in mind that Mata Rani resides only in clean places. Apart from this, keeping dirt in the house increases poverty.
Cleanliness of the kitchen should be taken care of before the start of Chaitra Navratri.
Because Goddess Annapurna resides here. Therefore, even before the start of Chaitra Navratri, tamasic things like garlic and onion should be thrown out of the kitchen.
Make Swastika on the main entrance of the house.
Before any auspicious work, Swastik is definitely made in home or temple. Therefore, before starting the puja on the first day of Chaitra Navratri, Swastika should be made on the main entrance of your house.
Pay attention to the south-east direction of the house
According to the scriptures, Goddess Durga resides in the south direction. Therefore it is auspicious to worship in this direction. You should establish ghat in this direction. Keep in mind that while worshiping Mata Rani, your face should be towards south or east direction.
