। ॥ ७८ ॥
In plain words
A still whirlpool of the Gaṅgā; the small basin at the root of the downy vine whose two buds are your breasts; the fire-pit of the flower-arrowed god's blaze; Rati's pleasure-house—your navel, daughter of the mountain, surpasses every image as the cave-entrance through which Giriśa's eyes attain Siddhi, their fulfilment.
Close to the Sanskrit
A still whirlpool of the Gaṅgā; the delicate root-basin of the creeper that is the line of down bearing the buds of your breasts; the fire-pit of the blaze of the flower-arrowed god; the pleasure-house of Rati; something indescribable—your navel, O daughter of the mountain, triumphs as the cave-mouth of Siddhi, attainment, for the eyes of Giriśa.
