Why Radharani is worshiped by the devotees? His (her) spirit is like that. If anyone, She finds a nice devotee of Krsna, She immediately recommends to Krsna, “How nice this devotee. He can render better service than Me. Please accept him.” This is spiritualism. This is spiritualism. Who can give better service than Radharani? She is so great that She is captivating Krsna. Krsna captivates Madana, Cupid. But Radharani captivates Krsna. How great She is. Radhe jaya jaya madhava-dayite. We pray always,

tapta-kancana-gaurangi
radhe vrndavanesvari
vrsabhanu-sute devi
pranamami hari-priye

[I offer my respects to Radharani, whose bodily complexion is like molten gold and who is the Queen of Vrndavana. You are the daughter of King Vrsabhanu, and You are very dear to Lord Krsna.]

The most dear, most beloved by Krsna is Radharani, and She is so humble. As soon as a humble devotee approaches Radharani by glorifying Krsna, immediately She accepts, “Oh, how great he is, he is doing greater service than Me.”
