Conical creations of cow dung decorated with flowers is the Bathukamma, this is a folk art. The immersion is done with great devotion, accompanied by rhythmic drum beats throughout the state of Telangana.
The myth is that the Chola King Dharmangada had a wife after many years of being married. The girl child was believed to be the incarnate of Goddess Lakshmi, the goddess of prosperity. The girl child survived many accidents, hence was called Life=Bathuku, and Amma= mother also used affectionately to address a female child.
The festival connects and celebrates nurturing. The girls are made aware of their own nurturing energy. There is of course the prayer to the goddess of health and wealth to bring prosperity to their families.
There are other legends and myths that are either around this. Some are adaptations of the mainstream religion. Like one that says it is the spirit of Parwati, since Parwati is the re-incarnation of Sati and Bathkuamma is the mother who came back to life.
Another popular myth is that the Goddess Gauri who is fatigued after her fierce war with mahishasura the demon, goes to sleep on the day after the new moon, and the celebrations are to awaken her, she awakens only on the day of Dashmi.
The variation to the Chola legend is that the Chola king Dharmangada and his wife Sathyavati lost 100 sons in a battle before the goddess incarnated in their house. the seers and sages who came to bless the child blessed her with immortality, ”Bathukamma or live forever.”
The Bathukamma is believed to be a lover of flowers, so flowers are arranged on a square wooden plank or bamboo frame of tapering sizes to form a pinnacle on top. This resembles the shape of a temple or gopura, the symbolic idol of Gowrie in turmeric is placed on top of the flowers. This becomes the Bathukamma
