Beneath the mandala's central square(s) is the space for the formless shapeless all pervasive all connecting Universal Spirit, the Purusha. This space is sometimes referred to as garbha-griya (literally womb house) - a small, perfect square, windowless, enclosed space without ornamentation that represents universal essence. In or near this space is typically a murti. This is the main deity image, and this varies with each temple. Often it is this idol that gives it a local name, such as Vishnu temple, Krishna temple, Rama temple, Narayana temple, Siva temple, Lakshmi temple, Ganesha temple, Durga temple, Hanuman temple, Surya temple, and others. It is this garbha-griya which devotees seek for ‘‘darsana'' (literally, a sight of knowledge, or vision).
