By Swami Harshananda
Certain categories of the images of Viṣṇu whose installation and consecration help in rites for the destruction of enemies, are classed under the ābhicārika type. These images, whether in the standing, sitting or lying posture, are bereft of beauty or symmetry. Emaciated body, dark complexion, dark clothes and a shrunken countenance with the eyes turned upwards characterize such murti-s. They are, as a rule, established in the outermost periphery of the village or town, known as the 'paisācapada', in inaccessible places like mountain tops or thick jungles. Prān prathiśtha (installation) is done during inauspicious moments and worship is conducted through mantras.
