When one is sufficiently eager to achieve success in devotional service, that eagerness is called samutkantha. This means complete eagerness. Actually this eagerness is the price for achieving success in Krsna consciousness. Everything has some value, and one has to pay the value before obtaining or possessing it. It is stated in the Vedic literature that to purchase the most valuable thing, Krsna consciousness, one has to develop intense eagerness for achieving success. This intense eagerness is very nicely expressed by Bilvamangala Thakur in his book Krsna-karnamrta. He says, "I am eagerly waiting to see that boy of Vrndavana whose bodily beauty is captivating the whole universe, whose eyes are always bounded by black eyebrows and expanded like lotus petals, who is always eagerly glancing over His devotees and therefore moving slightly here and there. His eyes are always moist, His lips are colored like copper, and through those lips there comes a sound vibration which drives one madder than a mad elephant. I want so much to see Him at Vrndavana!"
In the same Karnamrta there is another statement about the chanting of Radharani. It is said by one of the associates of Radharani: "O Lord Govinda, the girl who is the daughter of King Vrsabhanu is now shedding tears, and She is anxiously chanting Your holy name-Krsna! Krsna!"
This attachment for chanting the glories of the Lord is also stated in the Karnamrta as follows: "What shall I do for Krsna, who is pleasing beyond all pleasurable conceptions, and who is naughtier than all restless boys? The idea of Krsna's beautiful activities is attracting my heart, and I do not know what I can do!"
