Firstly, why Kamala Nayana? Why did the poet not use any other flower as a tribute to the lovely eyes of the Lord? First explanation is from the Ramayana, during the incident when Rishi Vishwamitra asks Dasaratha to allow Lord Rama and Lord Lakshamana to come with him :) Here, King Dasharatha deftly mentions his beloved son as "Rajeeva Lochana" to his advantage. He hints to Rishi Vishwamitra, that he young boy's has eyes like the lotus, which blooms during the day and rests at night. He is tender and not exposed to violent ways of Rakshasas, who operate by the night. Dasharatha thus argues that it is not proper for Lord Vishwamimtra to ask such a tender boy to protect the ashram from asuras.
There is another interesting observation. Lord Vishwamitra argues his way with Lord Dasharatha, and then takes Lord Rama and Lord Lakshamana along. The princes are fatigued after such a long and arduous journey. They fall asleep in the forest. Lord Rama is most charming even when is he is sleeping. Think of the Lord who is the personification of Lavayam and Soundaryam. How beautiful would the lord have been in his yoga nidra :) Now, Vishwamitra wants to wake the young children from their blissful sleep. How many of us have the divine fortune to see Lord Rama and Lord lakshamana in yoga nidra? (absolute bliss) Who would have the heart to wake such wonderful children from their sleep? So, he addresses them with suprabatham and then he addresses Lord Rama as "uthista kamala kantha" (wake up, O lotus eyed one) :) I am sure, he must have realized how right Dasharatha was, when he addressed his son as Kamala kantha :)
Secondly, there are so may flowers like Sunflower (Supatra, Varada in Samskrit). Why did the poet not use these names in this context? After all, the Lord was from Surya Kula, he could have pick sun flower in this context. The upanyasakar had a wonderful observation. The Lord's eyes are brimming with Karuna for his devotees. Hence, the poet wanted a flower that grows on water and conceals the water, just like his eyes are representation of the Karuna that wells in his heart from the bhakatas. Hence, the flowers that grow on land are no good :)
Another section of this poem, the poet uses the word "Kama janaka" for Maha Vishnu? How is this relevant? The upanyasakar has 2 wonderful observations on this !!
Firstly, Kama is the source of all desires and represents all things beautiful :) So, if Lord Krishna is addressed as Kama Janaka, or father of Kama, how beautiful must the Lord be :) After all, Lord Rama is endowed with both Lavanyam and Soundaryam :)
Secondly, lets take an example of a son, who is naughty. Who do you go to complain and correct the behavior? Of course, you go with the legitimate complaint to his father and say that his son is disturbing you. The righteous father will ensure that he takes corrective measure. Here, in this world, we are all tormented by various desires or kaama. Who do we take refuge in? Take refuge in the lotus feet of Lord Vaasudeva, whos is Kama Janaka and he will protect as all :)
