What happened to the Lord when he departed after fulfilling the purpose of his avatara?
That beauteous form with all the auspicious marks in which He manifested Himself in flesh
and blood to the people of His time is preserved for all time in the sanctified idols of
our temples Among the more famous of these shrines is Guruvayur, known as "Bhooloka
Vaikuntha" where the Lord reveals Himself to His devotees in the same majestic form
in which He welcomes them in Vaikuntha, His celestial abode.
The glory of Guruvayur was revealed by the Sage Dattatreya to King Janamejaya,
the son of Parikshit who became a victim of leprosy following a sarpa yajna or snake
sacrifice ht, performed to avenge his father's death brought' about by the deadly
Takshaka, Naga chieftain Janamejaya obtained no relief from medicines. Ultimately He was
advised by sage Dattatreya to worship the image of Sri Krishna at Guruvayur. Janamejaya
did so with single-minded devotion and penance for four months. And cured he was of the
festering and disfiguring sores of the body.
