Why do we use the term ‘image’ rather than common terms like ‘idol’ or ‘icon’? The latter two terms are considered pejorative in the context of Judaism, Christianity and Islam, whose orthodox sects condemn ‘idolatry’ or the worship of ‘idols’ or ‘icons’.
India’s classical texts used words like murti, vigraha, pratima, rupa, etc., to designate images, often statues, used for worship in temples or homes. In English, ‘image’ is a neutral term.
