Preface
From bottom to top, there are seven Rajus everywhere.
In the exact middle part of this fourteen Rajus high Loka, there is a Raju long, a Raju wide, and fourteen Rajus high Loka Nadi, which is also called Trasanadi because it is the abode of Trasa Jivas. In the lower Loka, within this Trasanadi, there are seven Naraks where Nāraki Jivas reside. In the middle Loka, within this Trasanadi, there are innumerable islands and oceans that are situated encircling each other. Among them is the Jambū Dvīpa, which is one lakh Yojana in expanse. In its exact middle is the Sumeru Mountain, which is one lakh Yojana high. All the Lokas below the base of this Sumeru are called the Lower Loka, and the Lokas above the peak of Sumeru are called the Upper Loka. In this Upper Loka, there are sixteen Svarga, nine Anudisa, and five Anuttara, where the Devas reside. In fact, Sumeru itself divides the three Lokas. The area with one Raju expanse and one lakh Yojana height is called the Middle Loka, as it is here that the Manuṣya and Tiryañca Jivas reside, hence it is also called the Nara-Tiryag Loka. Surrounding the Jambū Dvīpa is the Lavaṇa Samudra, which is two lakh Yojana wide. Surrounding it is the Dhātakīkhaṇḍa Dvīpa, which is four lakh Yojana wide. Surrounding it is the Kālodadhi Samudra, which is eight lakh Yojana wide. Surrounding it is the Puṣkara Varṣa Dvīpa, which is sixteen lakh Yojana wide. In the exact middle of this Dvīpa is the Mānuṣottara Mountain. Beyond this mountain, neither any human resides nor can one go, hence it is called Mānuṣottara. Thus, the area of one Jambū Dvīpa, one Dhātakīkhaṇḍa Dvīpa, and half Puṣkara Varṣa Dvīpa is called the Manuṣya Loka. Its width in the middle part is forty-five lakh Yojana as per the diameter of the Sūcī. Beyond this, all the innumerable islands and oceans end with the Svayambhūramaṇa Samudra. The Middle Loka ends here. These innumerable islands and oceans are called the Tiryag Loka as only Tiryañca Jivas are found there. The volume of the Manuṣya Loka is forty-five lakh Yojana. The volume of the Tiryag Loka is one Raju, which is also the volume of the Middle Loka. The volume of the Lower Loka is 196 Ghanarājus, and the volume of the Upper Loka is 147 Ghanarājus. The total volume of the Lokaākāśa is 343 Ghanarājus.
