There have been several controversies around the ceremony, including the Shankaracharyas objecting to the pran pratishtha since the temple is incomplete…
Some issues are deliberately false: That four Shankaracharyas opposed the ceremony was utterly a media creation. Of the four, two had their respective math administrations issue a press statement supporting the pran pratishtha. The third has also given interviews in support. As for the fourth, and I say this with all restraint, his claim to be a Shankaracharya is subjudice, and he has opposed it. Temples remain under construction for years, but that couldn’t be a reason not to perform pran pratistha. In the Hindu tradition, pran pratishtha can take place once the garbha griha, the sanctum sanctorum, is complete. The temple belongs to all sects, whether Shaiva or others. We must remember that Lord Ram did pran pratishtha of an idol of Shambhu at Rameshwaram, and that idol did not even have a canopy.
