Please don't get offended and i'm just curious. According to Skanda Purana, Goddess Sati self immolated in Swayamabhuva Manvanatara of Pitri Kalpa. She was born again as Parvathi Devi at beginning of current Vaishvara Manvantara of Swetha Varaha Kalpa. When Lord Rudra was carrying her body, Lord Narayana used His Sudarshana Chakra which cut Her body into different parts and these organs had fallen in different locations on Earth and these places are called as Shakti Peeths.
But at the end of Kalpa, Rudra destroys Earth. But i'm not sure about transition times of Pitri Kalpa and Swetha Varaha Kalpa, as Lord Vishnu's Avatar Varaha rescued Earth from demon Hiranyaksha who hid Earth in waters. So, i think Earth was not destroyed by Rudra at end of Pitri Kalpa. Still people worship the Shakti Peets of Previous Kalpa where Goddess organs are well preserved and worshipped with high veneration. So, my questions are
- Was Earth destroyed at end of previous Kalpa? If Yes, how Goddess organs were preserved during Pralaya?
- Generally, what happens to Idols in various temples at the end of Kalpa? I think temples are built only in Kali Yuga. Is this true?
- There's a legend for Holy City of Kashi where it will be not be destroyed even at at end of Kalpa. So, is there any story for these Shaktipeets in particular and other temples in general?
