Shiva
Shiva-related literature developed extensively across India in the 1st millennium CE and through the 13th century, particularly in Kashmir and Tamil Shaiva traditions. The monist Shiva literature posit absolute oneness, that is Shiva is within every man and woman, Shiva is within every living being, Shiva is present everywhere in the world including all non-living being, and there is no spiritual difference between life, matter, man and Shiva. The various dualistic and monist Shiva-related ideas were welcomed in medieval southeast Asia, inspiring numerous Shiva-related temples, artwork and texts in Indonesia, Myanmar, Cambodia, Laos, Vietnam, Thailand and Malaysia, with syncretic integration of local pre-existing theologies.
