Sree Sree Guru Gaurangau Jayatah!
Srila Rupa Gosvami has written this song:
bandhu sange yadi tava ranga parihas thake abhilas
tabe mor katha rakha jeyo naka jeyo naka
vrindavane kesi-tirtha ghater sakas
nayane bankima-dristi mukhe manda-has
It says, if you desire to amuse yourself with your friends, you should not go to Vrindavana, and even if you go, you should especially not go to Kesi Ghat. There is a danger lurking there. What is that danger? It is Sri Hari, Krishna Himself, Who has taken the form of Govinda: govinda-vigraha dhari. The danger is that if you go there and see Him, if you have got a vision of Govinda, you will not be able to return to the customary amusements of your ordinary household life.
The look of His eyes, His crooked glance, is very dangerous: nayane bankima-dristi mukhe manda-has. He is not standing straight, but tri-bhanga, with three curves. If this Krishna enters you, He will not come out. If Narayana enters, He may come out. Narayana is straight. But Krishna is curved like a hook and that is dangerous.
His color is like the color of a rain cloud: varna samujjvala shyam. You will find that in the springtime the leaves of the trees are so fresh. Similarly, Krishna is not old, but rather, a young adolescent. The lips of His mouth are very dangerous, and if you see the peacock feather on His head, you will not be able to come back to your household life. So, if you want to have fun with your friends, you should not go to Vrindavana, and should not see Krishna.
But unfortunately, we go to Vrindavana and still come back. We do not have such devotion. If anybody truly had the greed for Govinda, he could not return to his mundane life. His worldly relations would be destroyed. Greed for devotion is developed by associating with the pure devotees of the Lord. By their grace, it becomes possible for us to attain Krishna prema, divine love for God, the ultimate goal of life.
