Though the Indian temples are built in a pattern native to a particular region, the structure of Hindu temples is based on 4 collective principles of human life : they are Artha (wealth, prosperity), Kama (pleasure, sex), Dharma (ethics, values), Moksha (self-realization, freedom from life or reaching heaven!). In this transient world, we must do our duty correctly as we progress in age. Self-contentment promotes happiness.

North Indian temple design: They have a square garbagriha with adjacent pillared mandapas (halls or porches) that are connected to a sanctum by a vestibule (antaralas). Unlike south Indian temples the ones in the north have embellished entrance to the sanctum with figures of deities and geometric ornamentation. The temples usually contain a shrine and a meditation hall to engage in silent prayer and meditation. They are basically squares with several gradual projections in the center of each side. This gives a cruciform shape with a number of re-entrant angles on each sides .
Normally, a gopura is built with an enormous stone base in a rectangular plan and a superstructure of brick above it with support. It is topped by a barrel-vault roof crowned with a row of finials. Height, size, etc differ from temples to temples. But the main plan of the temple is the same. It is quite interesting to note that the height of Vimana over the inner sanctum is not uniform across India. Among the temples of East India where Kalinga style of architecture is predominant, the Vimana is the tallest structure. This is also true of north and West India where the tower with Vimana rises to a great height above the sanctum. On the contrary, in most of the south Indian temples, the Vimana over the inner sanctum is very much shorter than the entrance gate tower or towers (gopuras) on all four sides - East, west, north and south. With exceptions, this is a typical Dravidian style of temple architecture.
The terminology also differs as in the case of the superstructure over the garbhagriha, it is referred to as a 'shikhara'. But, as far as south Indian temple architecture is concerned, the term shikhara means a dome-shaped crowning cap above the Vimana. Among the entrance gate towers -gopura at four directions on the outer most walls, the East one is the main entrance to the temple. Rest of the gateways under the gopura are opened on certain auspicious days. The belief has been that if you choose one of these gate ways, you are assured of salvation, a place in heaven (Swargham) - meaning no rebirth will haunt you.
The tower/ vimana over the inner sanctum does not get as much importance as the entrance gate towers on the outer walls. In a few temples the roof of the sanctum assumes much importance regardless of its size, shape and height.
