Srimad Bhagavatam Canto 07, Chapter 04, Text 16

SB 7.4.16

akrsta-pacya tasyasit
 sapta-dvipavati mahi
tatha kama-dugha gavo
 nanascarya-padam nabhah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
As if in fear of Hiranyakasipu, the planet earth, which consists of seven islands, delivered food grains without being plowed. Thus it resembled cows like the surabhi of the spiritual world or the kama-dugha of heaven. The earth yielded sufficient food grains, the cows supplied abundant milk, and outer space was beautifully decorated with wonderful phenomena.
