In the verse we are discussing are the words “amusya-rupam”, meaning “that very form”. The ladies of Mathura are saying, “We are seeing Krsna, but why are we not feeling the highest prema? What austerities did the gopis perform to be able to see with the eyes of mahabhava the original form of Krsna adorned with a peacock feather in His crown and the very essence of all loveliness?” Unable to see that form of Krsna which the gopis see and unable to experience the mahabhava of the gopis, they wanted to know which austerities they could perform to become similarly fortunate.
Not everyone will be able to feel such elevated bhava. When our gurudeva Sri Srimad Bhakti Prajnana Kesava Gosvami Maharaja would dance, he would move in an exceptionally sweet and lovely way. With his eyes turned upwards and holding his sannyasa danda in his hand, he would dance immersed in bhava. I have never seen such dancing as his in all my life.
Whenever he would hear Krsna’s pastimes he would become emotional and begin weeping, and if we perform bhajana sincerely with resolute determination, we may also one day experience some of this bhava. We desire these feelings as do the ladies of Mathura who lamented, “Haya! Haya! We are seeing Krsna directly, yet we cannot experience the bhava of the gopis. Our lives are useless!”
