In Shaivism of Indonesia, the popular name for Shiva has been "Batara Guru", which is derived from Sanskrit "Bhattaraka" which means "noble lord". He is conceptualized as a kind spiritual teacher, the first of all Gurus in Indonesian Hindu texts, mirroring the Dakshinamurti aspect of Shiva in the Indian subcontinent. However, the Batara Guru has more aspects than the Indian Shiva, as the Indonesian Hindus blended their spirits and heroes with him. Batara Guru's wife in southeast Asia is the same Hindu deity Durga, who has been popular since ancient times, and she too has a complex character with benevolent and fierce manifestations, each visualized with different names such as Uma, Sri, Kali and others. Shiva has been called Sadasiva, Paramasiva, Mahadeva in benevolent forms, and Kala, Bhairava, Mahakala in his fierce forms. The Indonesian Hindu texts present the same philosophical diversity of Shaivism traditions found on the subcontinent. However, among the texts that have survived into the contemporary era, the more common are of those of Shaiva Siddhanta (locally also called Siwa Siddhanta, Sridanta).
