though many Indians may refer to casually as an idol, is more formally known as a murti, or the main worshippable deity, who varies with each temple. Often this murti gives the temple a local name, such as a Vishnu temple, Krishna temple, Rama temple, Narayana temple, Shiva temple, Lakshmi temple, Ganesha temple, Durga temple, Hanuman temple, Surya temple, etc. It is this garbha-griya which devotees seek for darsana (literally, a sight of knowledge, or vision). Above the vastu-purusha-mandala is a superstructure with a dome called Shikhara in north India, and Vimana in south India, that stretches towards the sky. Sometimes, in makeshift temples, the dome may be replaced with symbolic bamboo with few leaves at the top. The vertical dimension's cupola or dome is designed as a pyramid, a cone or other mountain-like shape, once again using the principle of concentric circles and squares. Scholars suggest that this shape is inspired by the cosmic mountain of Meru or Himalayan Kailasa, the abode of the gods, according to Vedic mythology. In larger temples, the central space typically is surrounded by an ambulatory for the devotee to walk around and ritually circumambulate the Purusa, the universal essence. Often this space is visually decorated with carvings, paintings or images meant to inspire the devotee. In some temples, these images may be stories from Hindu Epics; in others, they may be Vedic tales about right and wrong or virtues and vice; in yet others, they may be murtis of locally worshipped deities. The pillars, walls and ceilings typically also have highly ornate carvings or images of the four just and necessary pursuits of life – kama, artha, dharma and moksa. This walk around is called pradakshina. Large temples also have pillared halls, called mandapa — one of which, on the east side, serves as the waiting room for pilgrims and devotees. The mandapa may be a separate structure in older temples, but in newer temples this space is integrated into the temple superstructure. Mega-temple sites have a main temple surrounded by smaller temples and shrines, but these are still arranged by principles of symmetry, grids and mathematical precision. An important principle found in the layout of Hindu temples is mirroring and repeating fractal-like design structure, each unique yet also repeating the central common principle, one which Susan Lewandowski refers to as "an organism of repeating cells".
