Oh ! Rama, the legatee of Raghu's dynasty, thus sixty thousand square yojana-s of the earth was dug over, so as to make the earth's outermost plane as the unsurpassed rasaatala, the sixth subterranean and the nethermost plane. [1-39-21]
एवं पर्वतसंबाधं जम्बूद्वीपं नृपात्मजाः | खनन्तो नृपशार्दूल सर्वतः परिचक्रमुः ||१-३९-२२
Oh ! the tigerly king Rama, the sons of Sagara endeavoured everywhere digging over the Jambu Island which was verily congested with mountains in this way. [1-39-22]
