There are several literary works extolling the glory of the Lord of Guruvayur. The Narayaneeyam which is described as the Gospel of Guruvayur is the greatest of all, creating a Guruvayur in the hearts of everyone who reads or listens to it. The author of this great work is Meppattur Narayana Bhattatiri, one of the foremost sanskrit poets and savants of Kerala. Bhattatiri's guru was Achyuta Pisharadi who was his mentor and who weaned him away from the wayward path he was following to become a great devotee of the Lord. When Pisharadi was stricken with rheumatism, Bhattatiri took it over on himself by way of Guru dakshina. His Guru was cured and no amount of treatment could cure Bhattatiri. He then went to Guruvayur, sat before the Lord and composed 1034 slokas in the praise of the Lord and recited them before the diety. The slokas are divided into 100 dasakas (sets of 10 verses). Every one of the 100 dasakas ends with a prayer to the Lord of Guruvayur for relief of his disease. It is said that the Lord personally accepted the poem by signifying his approval and also by giving him advice whenever the poet was at a loss for words. For eg., while dealing with the Lord's incarnation as Narasimha, the poet could not visualise his form.

There upon the Lord himself sprang out of a pillar in the temple as Narasimha. The Lord himself enacted Krishna dancing on the Kaaliya and the Kaaliya mardhanam slokas in the Narayaneeyam are set to the same tempo as Sri Krishna's dance. According to Bhagavatham, Sri Krishna, as a child, broke a pot with a grinding stone whereas Battatiri wrote that it was with a churning stick. While he was grieving that he got it wrong, the Lord himself said that he had broken the pot both with the churning stick and the grinding stone. Narayaneeyam contains the essence of Bhagavata. Though its aim is the cure of ills of the present birth, it's ultimate aim is moksha or liberation from the cycle of births and deaths. In the last dasaka "Agre pashyami" (HIM I SEE BEFORE ME), the poet has given an inspired and inspiring vision of Srikrishna as Venugopal that was given to him by the Lord. This was on Ekadesi day.
