Krishnanattam.

APantomime, written by Raja Manaveda, who ruled as Zamorin of Calicut from 1655 - 58  A.D. It is based on Bhagavatha, particularly Dasama and Ekadasa Skanthas.  This unique art exists only in the Guruvayur temple.
Raja Manaveda was a contemporary of Melpathur, Poonthanam and Vilwamangalam II. The belief goes that the poet was, with the help of Vilwamangalam. was able to see Sree Krishna, and enchanted he rushed forward to embrace Him. Saying "Vilwamangalam told me ot this" He vanished and the poet was able to get hold of only a single peacock feather from the Peelithirumudi of the Lord. Using this feather the Zamorin made a Mudi and to enable this Peelithirumudi to be used on stage he composed a dance drama, naturally it was based on the story of Sree Krishna. 
Raja Manaveda a born genius, was not only a deep scholar and poet, but was an erudite master in all extant art forms. The poet followed the ancient dance forms of Koothu Koodiyattam and Theyyam. he depended on Jayadevas Geethagovinda. must have been also influenced by Ashtapadiyattam a dramatised version of Geethagovindam.
The story is divided into eight parts to be presented on stage on consecutive eight nights. namely Avatharam the incarnation of Maha Vishnu as Krishna; Kaliyamardhanam; Rasakreeda; Kamsavadham; Svayamvaram; banayuddham; Vividayudham and Swargarohanam.

Ground racing g to meet

It feels like the ground is racing to meet Ramanujacharya when he is brought out in a procession.
The devotees of this age feel blessed that they were able to show their love and regard for a master so great that he was called none less than a god. the celebrations that were conducted in all the places be it a large one or small place the connection felt so good even after so many years one felt blessed just to be associated in celebrating this great saint.( for mankind through the ages has found no parallel.) It is rightly said then all those even associated with the great Emberumanar are a special lot. there is a sort of satisfaction among the devotees for having had an opportunity to be part of this great celebration. Be blessed folks and continue the great work handed down to us by our Lord and saint Sri Ramanujacharya.

Ther Aalan Oh! owner of the chariot.

From anothers post. Parakala Nayaki is standing next to a person whose identity she is not certain about. However, she describes the person through the following events:

(1) Siva and Brahma beheld this form of the person in amazement;

(2) People of the three worlds were singing paeans to this person; the sounds of which resembled tempestuous sea waves.

Parakala nayaki accosts this “half-man, half-lion” form of the person who had hairs like manes and whose teeth resembled battle swords and asked him about his identity.

The person replied: “I am the resident of Ashtabhuyakaram. I took residence here not just to help Prahalahada in times of yore but to also help people like you.”

Parakala Nayaki is able to clearly explain the attributes of the person she saw in Ashtabhuyakaram.
