"Krishna once dressed Himself up exactly like Srimati Radharani, just to create fun among His friends. By seeing this dress, Krishna's friend Subala became very astonished." (Srila Rupa Goswami in The Nectar of Devotion)
"Standing with a symmetrical landscape of yellow flowering creepers emerging from the greenery of trees, Radha, holding Krishna's flute, has donned her divine lover's peacock-feather crown and saffron-colored dhoti. Blue-complexioned Krishna, in turn, wears Radha's earrings, red skirt, blouse, and transparent shawl. Holding hands, the two gaze into one another's eyes.
This unique visual motif of the clothing exchange serves as a metaphor for Radha and Krishna's shared essence. Radha's and Krishna's donning of each other's garments signifies that the two are identical, as is suggested in this verse by an unknown poet.
She wears his peacock feather, he dons her lovely, delicate crown; She sports his yellow garment, he wraps himself in her beautiful sari How charming the very sight of it. . . The daughter of Vrsabhanu [Radha] turns [into] Nanda's son [Krishna], and Nanda's son, into Vrsabhanu's girl. (Translation Srivasta Goswami, The Divine Consort, 87)
