"In Vrndavana all the pure devotees pray for the mercy of Srimati Radharani, the pleasure potency of Lord Krsna. Srimati Radharani is a tenderhearted feminine counterpart of the supreme whole, resembling the perfectional stage of the worldly feminine nature. Therefore, the mercy of Radharani is available very readily to the sincere devotees, and once She recommends such a devotee to Lord Krsna, the Lord at once accepts the devotee's admittance into His association. The conclusion is, therefore, that one should be more serious about seeking the mercy of the devotee than that of the Lord directly, and by one's doing so (by the good will of the devotee) the natural attraction for the service of the Lord will be revived."
Srimad-Bhagavatam, 2nd Canto, 3.23
"Once Lord Krsna considered with His heart: 'Everyone says that I am complete bliss, full of all rasas. All the world derives pleasure from Me. Is there anyone who can give Me pleasure? One who has a hundred times more qualities than Me could give pleasure to My mind. One more qualified than Me is impossible to find in the world. But in Radha alone I feel the presence of one who can give Me pleasure.
Although My beauty defeats the beauty of ten million cupids, although it is unequalled and unsurpassed and although it gives pleasure to the three worlds, seeing Radharani gives pleasure to My eyes. The vibration of My transcendental flute attracts the three worlds, but My ears are enchanted by the worlds of Srimati Radharani. Although My body lends fragrance to the entire creation, the scent of Radharani's limbs captivates My mind and heart. Although the entire creation is full of different tastes because of Me, I am charmed by the nectarean taste of the lips of Srimati Radharani. And although My touch is cooler than ten million moons, I am refreshed by the touch of Srimati Radhika.
Thus although, I am the source of happiness for the entire world, the beauty and attributes of Sri Radhika are My life and soul. In this way My affectionate feelings for Srimati Radharani may be understood, but on analysis I find them contradictory. My eyes are fully satisfied when I look upon Srimati Radharani but by looking upon Me, She becomes even more advanced in satisfaction. The flutelike murmur of the bamboos rubbing against one another steals Radharani's consciousness, for She thinks it to be the sound of My flute. And She embraces a tamala tree, mistaking it for Me. 'I have gotten the embrace of Sri Krsna,' She thinks, 'so now My life is fulfilled. Thus She remains immersed in pleasing Krsna, taking the tree in Her arms. When a favorable breeze carries to Her the fragrance of My body, She is blinded by love and tries to fly into that breeze. When She tastes the betel chewed by Me, She merges in an ocean of joy and forgets everything else. Even with hundreds of mouths I could not express the transcendental pleasure She derives from My association. Seeing the luster of Her complexion after Our pastimes together, I forget My own identity in happiness.
The sage Bharata has said that the mellows of lover and beloved are equal. But he does not know the mellows of My Vrndavana. The happiness I feel when meeting Radharani is a hundred times greater than the happiness I get from meeting others.'"
