These have been dated to be from 6th century onwards. Of the numerous early to mid medieval era Hindu deity stone statues uncovered on Indonesian islands, at least 135 statues are of Durga. In parts of Java, she is known as "Loro Jonggrang" (literally, "slender maiden"). In Cambodia, during its era of Hindu kings, Durga was popular and numerous sculptures of her have been found. However, most differ from the Indian representation in one detail. The Cambodian Durga iconography shows her standing on top of the cut buffalo demon head. Durga statues have been discovered at stone temples and archaeological sites in Vietnam, likely related to Champa or Cham dynasty era. Durga is a major goddess in Hinduism, and the inspiration of Durga Puja – a large annual festival particularly in the eastern and northeastern states of India. One of the devotees of her form as Kali was Sri Ramakrishna who was the guru of Swami Vivekananda. He is the founder of the Ramakrishna Mission. Durga as the mother goddess is the inspiration behind the song Vande Mataram, written by Bankim Chandra Chatterjee, during Indian independence movement, later the official national song of India. Durga is present in Indian Nationalism where Bharat Mata i.e. Mother India is viewed as a form of Durga. This is completely secular and keeping in line with the ancient ideology of Durga as Mother and protector to Indians. She is present in pop culture and blockbuster Bollywood movies like "Jai Santoshi Maa". The Indian Army uses phrases like "Durga Mata ki Jai!" and "Kaali Mata ki Jai!". Any woman who takes up a cause to fight for goodness and justice is said to have the spirit of Durga in her.
