Excuse me, this Guruvayoor Lord Krishna's idol is not the one worshipped by Rukmini.(It is in Udupi installed by Madwacharya).Guruvayoor idol was worshipped by Devaki & Vasudev since their 3 past janmas when Lord Vamana & Lord Prashna Garbha was born as their son,as a boon from Lord Vishnu.It was given to them from Lord Brahma himself.When Janamajeya was suffering with Leprosy, he came to Guryvayoor to worship it. It was cured. The idol was rcvd by Lord Shiva & Parvathi for the installation at South end of India,after the end of Dwaparayoga.
