Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 8-9
Sanskrit:
तत्रत्यानां दिवसमध्यङ्गत एव सदाऽऽदित्यस्तपति सव्येनाचलं दक्षिणेन करोति ॥ ८ ॥ यत्रोदेति तस्य ह समानसूत्रनिपाते निम्लोचति यत्र क्वचन स्यन्देनाभितपति तस्य हैष समानसूत्रनिपाते प्रस्वापयति तत्र गतं न पश्यन्ति ये तं समनुपश्येरन् ॥ ९ ॥
ITRANS:
tatratyānāṁ divasa-madhyaṅgata eva sadādityas tapati savyenācalaṁ dakṣiṇena karoti; yatrodeti tasya ha samāna-sūtra-nipāte nimlocati yatra kvacana syandenābhitapati tasya haiṣa samāna-sūtra-nipāte prasvāpayati tatra gataṁ na paśyanti ye taṁ samanupaśyeran.
Translation:
The living entities residing on Sumeru Mountain are always very warm, as at midday, because for them the sun is always overhead. Although the sun moves counterclockwise, facing the constellations, with Sumeru Mountain on its left, it also moves clockwise and appears to have the mountain on its right because it is influenced by the dakṣiṇāvarta wind. People living in countries at points diametrically opposite to where the sun is first seen rising will see the sun setting, and if a straight line were drawn from a point where the sun is at midday, the people in countries at the opposite end of the line would be experiencing midnight. Similarly, if people residing where the sun is setting were to go to countries diametrically opposite, they would not see the sun in the same condition.
