Now Sri Jayadeva Gosvami will begin describing the Vasanta-rasa: "My heart is palpitating, for I desire to write such a thing which in this life I have not written before, and which is not mentioned anywhere: that Krsna will fall at the feet of Radhika. We know it well, but Krsna is the Supreme Controller, the cause of all causes, and the original bhagavat-avatara. That He falls at the feet of His own potency who is the form of His dasi" I don't know if this is proper, but my heart is saying that without Krsna putting His head at Her feet, She will not be appeased! I don't know if I am able to write it."
Jayadeva goes on to describe that on the plains of Giriraja Govardhana, at Candra-sarovara, Candra remained throughout the whole of one of Brahma's nights. What is the duration of Brahma's night? Millions of yugas. In order to witness the rasa-lila he stayed there, so it is called Candra-sarovara.
In the spring season, all of the fruits and flowers in Vrndavana come out. The she-crow starts her ...ku-ku sound, the peacock starts his ...ke-kah sound, and it is as if the pigeons are playing the conchshell, making their ...ko-ko sounds. They are all making their own sounds, and collectively it sounds as if they are playing a sahanai. In this way all of the birds and animals become happy, and there is no one who is not dancing. Forming groups, Krsna and the gopis start dancing. All young unmarried girls are present there, and they had been waiting for one year. For dancing with Krsna, for meeting Krsna"for a whole year a fire of separation had been burning inside them. Not for themselves, not for lust, but for mitigating this separation.
For really becoming immersed in Krsna's rasa, one must enter into this poetry composed by Jayadeva Gosvami. Therefore, Caitanya Mahaprabhu, His heart full of rasa, at night would tell Svarupa Damodara, "Please recite Gita-govinda for Me." Hearing it, immediately His pleasure would increase. Svarupa Damodara would read precisely what Caitanya Mahaprabhu desired to hear. Sometimes it was the poetry of Jayadeva, sometimes Candidasa, sometimes Vidyapati, and sometimes he would read verses from the five chapters describing rasa in the Srimad-Bhagavatam.
