The Visual Symbol of Devotion: The Long Sindoor
One of the most striking visual aspects of Chhath Puja is married women sporting a thick line of bright orange sindoor that stretches from the tip of their nose all the way up to their hairline.
The Symbolism
In Bihari and Purvanchali culture, the length of the sindoor is directly associated with prayers for the long life and prosperity of the husband. Applying it from the nose signifies the depth of the wife's devotion and her public declaration of prayers for an unbroken, thriving family lineage.
