Vijaya Dashami , the 10th and final day of the 10 days of Navaratri is a heavy hearted day .
In areas where Durga Puja is celebrated, it is believed that duing these 10 days starting from Mahalaya , Devi Durga with her entire brood of Lord Ganesha, Lord Karthik, Goddess Saraswati and Goddess Lakshmi visits her paternal home on earth , heaven being her husbands home .
These 10days are celebrated and worshipped as the daughters homecoming and also duing this time, the DIVINE LADY takes time off to slaughter Mahishasura , ( psst !!!a multi-tasker allright )
On the evening of Dashami, the idols are taken for "visarjan " or immersion in the nearby water bodies . Before that, the ladies of each locality of the nearby pandals go to the respective idols with sindoor or kumkum as we call it here in south india and give their daughter Durga a send off by smearing sindoor in the hair parting of the idol and on the face of the idol . This is a way to wish their daughter Devi Durga the " sada suhaagan" or " sumangali" blessing and send her off to her husband Siva's abode ,up above .
The married ladies then also apply the sindoor on each other to wish other long and happy married lives .This ritual is called " sindoor khela" . This is a Bengali custom but has also permeated into the neighbouring states .
The idols are then taken through the streets amidst beats of drums and chants and much dancing to be ritually immersed, to wait for another year to welcome the daughter home .
