Abstract: The Mizos of northeast India have their own unique culture and society with indigenous religious beliefs that were closely linked with their everyday needs and their world-views. For the Mizos the world was inhabited by spirits, some benevolent and some evil. The evil spirits were believed to cause all kinds of illnesses and misfortunes, and in order to recover from such illnesses the evil spirits had to be placated by sacrifices known as inthawina which can be understood as ‘ceremonial cures’. The Mizos lived in fear, always afraid of evil spirits, and their religious energies were centred on propitiating these evil spirits through frequent sacrifices. The Puithiams (priests) would officiate at such events. Christianity brought inevitable change in the Mizos’ religious and world-views. Nevertheless, many of the existing pre-Christian beliefs of Mizo society were adopted or modified by missionaries to help the Mizos to understand more fully Christian concepts and beliefs, especially with reference to the concepts of health and healing. It can also be argued that pre-Christian social, religious and cultural beliefs carried in them ‘theologies of life’ which were adopted by missionaries or those spreading the gospel message, thus allowing these practices, as well as Christian doctrines themselves, to be seen in a new light.
