The Indian city of Varanasi, Uttar Pradesh is said to be the most holy city in Hinduism. It is considered by many to be the most sacred place of pilgrimage for Hindus irrespective of denomination.
The “garbha griha” (literally womb-house or womb-chamber), the shrine inside a temple complex where the main deity is installed in an area that is in a separate building by itself inside the complex, is the most sacred site within the temple complex.
The garbha griha usually contains the murti (idol or icon), the primary focus of prayer. In temples with a spire or vimana, this chamber is placed directly underneath it, and the two them form a main vertical axis of the temple. These together may be understood to represent the axis of the world through Mount Meru. The garbha griha is usually also on the main horizontal axis of the temple which generally is an east-west axis. In those temples where there is also a cross-axis, the garbha griha is generally at their intersection.
