Seeing the Earth sinking from fear, the great Kashyapa held her on his lap; and because the great Rishi held her on his lap (uru) therefore is the Earth known by the name of Urvi.
तां दृष्ट्वा द्रवतीं तत्र संत्रासात् स महामनाः। ऊरुणा धारयामास कश्यपः पृथिवीं ततः॥ धृता तेनोरुणा येन तेनोर्वाति मही स्मृता।
