Once upon a time, Brighu and other saint perform yajna for welfare of all living beings, after the completion of yajna they should offer first respect to one among the trimurties (brahma, vishnu, shiva).They were confused, so Narada told him to test all three. When he reached satya loka, brahma and saraswathi were enjoying music played by saraswathi so they didn't see and welcome Brighu, he became insulted and cursed them they will not have any temple in earth. When he reached kailasam, he saw shiva and parvati dancing so they too didn't see and welcome brighu so he cursed shiva to be prayed only in lingam form and finally reached vaikuntham he saw vishnu sleeping in his serpent Anantha-Shesha. Vishnu knew Brighu was waiting but kept his eyes close, seeing the act he got angry and kicked his chest resulting vishnu to open his eyes, then he said that don't be angry with me Brighu rishi and he served him with utmost devotion and Brighu decide to offer first respect to him. After Brighu left Lakshmi left him as Brighu kicked vishnu chest where she resided. After that vishnu lost all his wealth and left vaikutham and roamed in earth in the name of Srinivasan.He stayed in an ashram which was taken care by a women, she is none other than yoshada krishna adopted mother in previous birth. He falls in love with a princess named Padmavati (reincarnated as lakshmi).They both agree to marry. Srinivasan took a loan from Kubera for the wedding expenses from the idea told by Narada. Srinivasan promised kubera to pay only interest until the end of kali yuga and will finally pay the original amount. After the marriage of Srinivasan and Padmavathi they decide to stay in earth till kali yuga ends to protect people and become god that is now known as (Thirumala Thirupathi).After some years many kings construct temple for him and so many people offer their service and devotion to him, in return he helped all the people when they ask for help. People till now believe that Srinivasan along with padmavathi amman will protect mankind with whatever good wish they ask.
