Vertically, the sun-globe is situated just in the middle of the universe, in Antarikṣa, the space between Bhūrloka and Bhuvarloka. The distance between the sun and the circumference of Aṇḍa-golaka, the globe of the universe, is estimated to be twenty-five koṭi yojanas (two billion miles). Because the sun enters the universe and divides the sky, it is known as Mārtaṇḍa, and because it is produced from Hiraṇyagarbha, the body of the mahat-tattva, it is also called Hiraṇyagarbha.
