Lord Jagannath...
...along with his elder brother Lord Balabhadra...
...& sister Devi Subhadra adorned Gajanana Besha
The Holy Trinity decked up in Hati Besha after a ceremonial bath at Snana Mandap.
Popularly called the Hati Besha or the Gaja Besha happens on the full moon day of Jyestha.
The deities get dressed in elephant attire after the sacred bath.
It is believed that the deities are dressed as Lord Ganesha to satisfy the followers of the Ganapatya sect.
As believed, in the 15th century, a devotee of Lord Ganesha named Pandit Ganapati Bhatt of...
... the Mahaganapatya community visited Srimandir for darshan of the Holy Trinity.
It was Devasnana Purnima & he witnessed the deities seated on the bathing altar.
However, he had a wish to see Lord Ganesha within Lord Jagannath. As he couldn’t see this, he returned with disappointment.
Lord Jagannath took the guise of a priest & stopped him, requesting him to return to the temple where he can see his Lord Ganesha.
When he came back to the temple, he danced with joy after seeing Lord Ganesha within Lord Jagannath.
Since that day...
...the ritual is being observed.
