How is the religious significance of Indian architecture reflected?

The most important buildings in Indian architecture are religious buildings, and even cities have religious meanings. Mario Bussagli pointed out that "the whole construction activity of Indian architecture has the significance of witchcraft ceremony: firstly, divination should be used to select the site, and demons, elves and other gods other than the main gods provided by the temple should be driven out of the site to ensure the harmonious correspondence between the site selection and the universe".
