Prabhupada: Don't take that Radharani is an ordinary woman, like we have our wife or sister or mother. No. She is the pleasure potency. And the birth of Radharani was not from the womb of any human being. She was found by Her father in the field. While father was plowing, he saw one little nice child is lying there, and he had no children, so he caught it and presented to the queen, "Oh, here we have got a very nice child." "How you got?" "Oh, in the field." Just see.

Radharani's janma is like that. So this janma is today, and Radha, this name is sometimes not found in Bhagavata. So the atheistic class of men protest that "Radharani's name is not in the Srimad-Bhagavatam. How this name came, Radharan i?" But they do not know how to see it. There is anayaradhyate. There are many gopis, but there is mention that by this particular gopi. He is served more pleasingly. Krsna accepts this gopi's service more gladly. Anayaradhyate. Aradhyate. This aradhate, this word, aradhyate means worshiping. From this word aradhyate, Radha has come. But Radha's name are there in other Puranas. So this is the origin.>>> Ref.
