That there is a temple for Ghosts in Kaanathur, near Kasargod, Kerala is a fact.
But that it holds spirits and gave out information that it was Pilot’s error that caused Mangalore Air crash, well. I take it with a pinch of salt.
“The temple is called Nalwaru, which litreally means 4 persons. However, the four persons at the temple are ‘gods of ghosts’! The four deities are Ugramurthy, Panjurli, Raktha-Chamundi & Vishnumurthy. This temple is very sacred, and people fear the deities of the temple. The temple is filled with a lot of tantric powers, very typical to any Keralite temple. The main purpose of this temple is that it servers as a people’s court. Most of the disputes are settled in the temple courtyard, this has been the practice for many decades now. A plaintiff with truth on his side can give a petition to the temple authorities. And defendant will receive a memo (similar to a court’s order) from the temple. If the defendant refuses to obey and decides not to respond to the orders from the temple, and decides not to show-up for hearing at the temple, such persons will be faced with sudden misfortunes, and sudden deaths in their family. Further more, It is also believed that such persons souls will be held by these 4 ghost gods. People in the region and in and around Mangalore, Karnataka are very scared of these 4 gods and do not even speak of these gods casually. Hence they normally show up to avoid the wrath of the ghost gods. It is to be noted that one of Mangalore’s air crash victims soul was held by one such Ghost gods, and after a lot of begging and cajoling by the victim’s family members the ghost gods released his soul, but did tell that all the victims soul from that crash is still held by them, they also confessed that it was not them that caused the accident, but a pilot’s error. Mangalore Airport’s runway was built after relocating a Ghost deity temple. This pilot’s error was later confirmed by the investigation team. The popular belief in this region is when a soul is held by a ghost god/s, the food prepared on their ”teethi” is untouched by the crows or any other animals. “
