Why do we say Radhey Radhey?

So many people are curious to know, why do we say Radhey Radhey? I mean, a simple answer is, go to Braj and see. Everywhere in Braj, that's how people greet each other, with ‘Radhey Radhey’. But, now you know some more of the philosophy behind it. That Radharani is Krishna Herself. And, if we want to please Krishna also, He loves to hear Radhey name. So, when Shree Kripalu Ji Maharaj teaches us about Radharani, and reveals kirtan about Radharani, sings Radhey Radhey, He is giving that to the world. Then make your own connection with Radharani.
