They appeared together on Gadadaye, the eastern horizon of Gauda. Gauda means sweet. Gaudadesha is the sweet country that is non different from Vrindavan, the land of sweetness, madhurya. As the sun and moon rise in the east, 'udaye' implies this direction. East is the spiritual direction, to which we shall turn to uncover the secret treasure of our spiritual inheritance.
Light arises in the east, the direction of the gods.
Gauda represents his sweetness, and udaya the eastern direction, that of his aisvarya. When he who is all majestic appears as if ordinary, this is truly sweet. When the two sweet Gods, Krsna and Balarama, appear as Krsna Caitanya and Prabhu Nityananda there is something more added to their sweetness. On the eastern horizon of the land of madhurya they appeared like the sun and moon, as if these two luminary orbs had simultaneously arisen. Kaviraja Goswami describes this as 'citrau,' brilliant and wonderful.
