The pyramidal structures in temples were constructed to enable human communication with the spirit world.

Gopurams (towers that will enable kings to sneak outside the world?) are typical Thamizh temple structures. They are found in every temple, some of the most inspiring are in Thiruvarangam, Thiruvilliputhur and Perivudayar temple at Thanjavur. The Egyptians, Mayans, Incas and Aztecs also had their own towers (Pyramids) for observation and astronomical research purposes. The gopurams also contain idols depicting gods, their consorts and hosts. The diabolical spirit world would be much pleased to communicate with those who are seeking to connect with their dark kingdom in such fashion.

According to Dr. Kabilan, there are wormholes in these structures that are actually passage-ways for the spirits (and the spirit possessed humans) to move between the physical and the spiritual world. (From a Vendhar TV documentary about the Big temple in Thanjavur, South India).We see this in even the south American Inca, Mayan and Aztec civilizations. India has a lot of these, particularly in south India where the dominant population is generally Dravidian and particularly Thamizh.
