When God assumed His Krishna Avatar and ended His divine pastime on earth, did He leave a human and material body like common people, or did He disappear by His Yoga Maya? I read sometime that His mortal remains were miraculously transported into Jagannath archa murti?

Lord Krishna lived for 125 years. Throughout His lifetime, He performed innumerable lilas. When it was time for Sri Krishna to give up His mortal coil and when all the gods and sages curiously awaited His final divine lila, the Lord disappeared into Srimad Bhagavatam. Srimad Bhagavatam is verily Sri Krishna.
