2.8.12

divasasya ravir madhye sarvakālaṃ vyavasthitaḥ
sarvadvīpeṣu maitreya niśārdhasya ca saṃmukhaḥ //

The glorious sun, Maitreya, darts like an arrow on his southern course, attended by the constellations of the Zodiac. He causes the difference between day and night, and is the divine vehicle and path of the sages who have overcome the inflictions of the world. Whilst the sun, who is the discriminator of all hours, shines in one continent in midday, in the opposite Dwípas, Maitreya, it will be midnight: rising and setting are at all seasons, and are always (relatively) opposed in the different cardinal and intermediate points of the horizon. When the sun becomes visible to any people, to them he is said to rise; when he disappears from their view, that is called his setting. There is in truth neither rising nor setting of the sun, for he is always; and these terms merely imply his presence and his disappearance.
