Guru Nanak during his travels came to Jagan Nath Pun. It is a very important place of pilgrimage of Hindus, situated on the sea shore, touching the Bay of Bengal. Lord Krishna and Vishnu are worshipped here as Jagan Natha, the Lords of the universe. Here a special kind of idol worship is performed with the usual formalities. It is known as Arti. It is said that in the evening when the priests performed Arti, Guru Nanak stood there as a silent spectator as if nothing was happening. He came out in the open and sang the following hymn;
"The entire sky is the silver plate. The Moon and the Sun are lamps. The luminous stars are studded in it like jewels. The wind was the scent of all flowers on earth. Thus worship performed,O Thou the destroyer of births!
And the unstruck melody of his word ringeth through the universe. Millions are Thy eyes and yet Thou has no eye. Millions are Thy feet and yet Thou has no feet, Millions are Thy noses and yet Thou has no nose, and through the Guru's instruction this light is illuminated, 0 people! that alone is worship that pleaseth my Lord. Like the honey is to bee, my mind cherishes the honey of His Lotus feet. OLord! allay the thirst of Nanak, thy Sarang, 0 Lord of Bliss!
So that he merges in His Name'.'
The place where Guru Nanak sang the above mentioned hymn, a Gurdwara called Mangu Math stands in his memory.
Puri, commonly called Jagannath Puri after the famous Hindu Temple of Jagannath, was visited by Guru Nanak Dev in 1509 during his eastern travels. He preached against idolatry and exhorted the people to sing praises of the One God, who is Formless and yet all forms are His. Gurdwara Baoli ahib and Mangu Math served by UDasi priests commemorate the Guru's visit. These were first established by Bhai Almast, the notable UDasi preacher, during the middle of the seventeenth century.
