Above all of them is the mädanäkhya mahäbhäva of Srimati Radharani in which even the most subtle selfish desires have vanished and which is even more pure than gold molten a hundred thousand times. In their books, Srila Rüpa and Sanätana Gosvami have elaborately described the love of Sri Sri  Rädhä-Mädhava with all detailed examples. The confidential love of Sri Sri  Rädhä-Mädhava, which was previously hard to comprehend even by Lord Brahmä and Uddhava, has been revealed by Srila Rüpa and Sanätana in their books in such a way that ordinary souls of the Kali age can easily comprehend as well as practise it. — “They have revealed such a love.”

From the writing of Ananta das babaji.

The Vedas take us to the natural exchange of love or rasa , that is exhibited in the spiritual realm, where Krishna who is known as Rasraja is waiting for us to exchange loving mellows with him , a playground of love with no karmic tinges
