Gauri Maa, believed to be a form of Devi Parvati and mother of Lord Ganesha, plays a vital role in Ganesh Chaturthi celebrations. In places like Versova Koliwada in Mumbai, her arrival symbolises the beginning of the festival. Worshipped for peace and prosperity, this tradition holds deep cultural roots, especially among Maharashtra’s Koli community where it's celebrated with devotion and joy.
