After the Hindu reformists identified Durga with India, she became an icon for the Indian independence movement. In the first quarter of the 20th century, the tradition of Baroyari or Community Puja was popularised due to this. After independence, Durga Puja became one of the largest celebrated festivals in the whole world. Durga Puja also includes the worship of Shiva, who is Durga's consort (Durga is an aspect of Goddess Parvati), in addition to Lakshmi, Saraswati with Ganesha and Kartikeya, who are considered to be Durga's children. Worship of mother nature is also done, through nine types of plant (called "Kala Bou"), including a plantain (banana) tree, which represent nine divine forms of Goddess Durga. Modern traditions have come to include the display of decorated pandals and artistically depicted idols (murti) of Durga, exchange of Vijaya greetings and publication of Puja Annuals.
