Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 7
Sanskrit:
एषां मध्ये इलावृतं नामाभ्यन्तरवर्षं यस्य नाभ्यामवस्थित: सर्वत: सौवर्ण: कुलगिरिराजो मेरुर्द्वीपायामसमुन्नाह: कर्णिकाभूत: कुवलयकमलस्य मूर्धनि द्वात्रिंशत् सहस्रयोजनविततो मूले षोडशसहस्रं तावतान्तर्भूम्यां प्रविष्ट: ॥ ७ ॥
ITRANS:
eṣāṁ madhye ilāvṛtaṁ nāmābhyantara-varṣaṁ yasya nābhyām avasthitaḥ sarvataḥ sauvarṇaḥ kula-giri-rājo merur dvīpāyāma-samunnāhaḥ karṇikā-bhūtaḥ kuvalaya-kamalasya mūrdhani dvā-triṁśat sahasra-yojana-vitato mūle ṣoḍaśa-sahasraṁ tāvat āntar-bhūmyāṁ praviṣṭaḥ.
Translation:
Amidst these divisions, or varṣas, is the varṣa named Ilāvṛta, which is situated in the middle of the whorl of the lotus. Within Ilāvṛta-varṣa is Sumeru Mountain, which is made of gold. Sumeru Mountain is like the pericarp of the lotuslike Bhū-maṇḍala planetary system. The mountain’s height is the same as the width of Jambūdvīpa — or, in other words, 100,000 yojanas [800,000 miles]. Of that, 16,000 yojanas [128,000 miles] are within the earth, and therefore the mountain’s height above the earth is 84,000 yojanas [672,000 miles]. The mountain’s width is 32,000 yojanas [256,000 miles] at its summit and 16,000 yojanas at its base.
