Mangalagiri

The temple tank is known as the Lakshmi Pushkarini. Legend has it that this pushkarini was created by the Gods, combining the waters from several holy rivers of the land, and that Mahalakshmi (who came out of the milky ocean when it was churned by the gods and the asuras), bathed in this pushkarini and married Vishnu thereafter.

Lord Shiva showed himself as Ksheeraramalingeswara and showed the child 

1. ksheerasamudra(ocean of milk),
2. Ghrutasamudra(ocean of ghee),
3. Amruta sagara(Sea of immortality), and 
4. lots and lots of tasty food.

Upamanyu was out raged in happiness seeing his Lord Shiva and Maa Paarvathi on Nandivaahana and worshipped them with joy and happiness.This was also a joyous moment for all the dieties and they showered the boy and Lord with flowers and sweet music. Upamanya was delighted and knelt before Lord and prąyed. Lord Ksheeraramalingeswara lifted the child with love and affection and kissed him and told Maa paarvathi that the child would be their son from that moment and assigned the boy with the leadership to all ganas(ganadhipathi).Maa Parvathi blessed him with a boon of being young throughout his life and offered the child Ksheerasamudra in the form of a ball. Lord Ksheeraramalingewara blessed Upamanyu with all the boons like the Ksheera samudra and all the tasty food that was with him.He also blessed the child with immortality and capacity to do Sambhavi vrata and Paasupata vrata. Lord was not satisfied with all the boons he gave to the child and asked for any other boon he wanted. Upamanyu innocently replied that inspite of all the boons he was given he would not be free from this worldly relations without complete and permanent devotion towards his Lord Shiva and asked Lord to stay with him and protect him throughout his life. Lord Shiva was happy and fulfilled the request of his child. From that moment He stayed there as Ksheeraramalingeswara with Maa Paarvathi and this place is called Ksheerapuri and now as Palakollu.
