Srimati Radharani did not express Her personal unhappiness at being separated from Krsna. She wanted to evoke Krsna's feelings for the condition of all others in Vrndavana-dhama-mother Yasoda, Maharaja Nanda, the cowherd boys, the gopis, the birds and bees on the banks of the Yamuna, the water of the Yamuna, the trees, forests and all other paraphernalia associated with Krsna before He left Vrndavana for Mathura. These feelings of Srimati Radharani were manifested by Sri Caitanya Mahaprabhu, and therefore He invited Lord Jagannatha, Krsna, to return to Vrndavana. That is the purport of the Ratha-yatra car's going from Jagannatha Puri to the Gundica temple.
