## First Understanding: The Description of Humans
**[103 types of humans exist]** They eat at intervals of one day and nurture their offspring for 79 days. In the five Hari Varsha and five Ramya Varsha regions, humans have a lifespan of two Palyopamas and a height of two Kos. They have Vajra-Rishabha-Naracha-Sanhanan (a specific type of head) and a square body structure. They desire food at intervals of two days. They have 128 ribs.
**[64 types of humans exist]** They nurture their offspring for 64 days. In the five Devakuru and five Uttar Kuru regions, humans have a lifespan of three Palyopamas and a height of three Kos. They have Bana-Rishabha-Naracha-Sanhanan (a specific type of head) and a square body structure. They have 256 ribs, eat at intervals of three days, and nurture their offspring for 49 days.
**[The term "Antar" means "middle"]** The islands in the middle of the Salt Ocean are called Antarvipas. There are 56 Antarvipas. The humans living in these Antarvipas are called Antarvipaj.
**[Location of Antarvipas]** These Antarvipas are located on the projections of the Himavan and Shikhari mountains that extend into the Salt Ocean. The Himavan mountain, which marks the boundary of the Bharat Kshetra in Jambudvipa, extends east-west into the Salt Ocean. Similarly, the Shikhari mountain, which marks the boundary of the Airvat Kshetra, also extends east-west into the Salt Ocean. Each end of these mountains is divided into two parts, resulting in two projections extending into the Salt Ocean. These projections are called "Daadha" due to their resemblance to elephant tusks. Each Daadha has seven regions inhabited by humans. Thus, there are 847 = 56 Antarvipas. The humans living in these Antarvipas are called Antarvipaj.
**[Four Islands in the Salt Ocean]** Three hundred Yojanas away from the Himavan mountain, in the Salt Ocean, there are four islands, each with a diameter of 300 Yojanas, located in the four directions: 1. Ekosak, 2. Prabhasik, 3. Vaishanik, and 4. Langalik.
**[Four More Islands]** Four hundred Yojanas further from these islands, there are four more islands, each with a diameter of 400 Yojanas, located in the four directions: 5. Hayakarna, 6. Gajakarna, 7. Gokarna, and 8. Shashkulokarn.
**[Four More Islands]** Five hundred Yojanas further from these islands, there are four more islands, each with a diameter of 500 Yojanas, located in the four directions: 9. Adarshamukh, 10. Medhamukh, 11. Ayomukh, and 12. Gomukh.
**[Four More Islands]** Six hundred Yojanas further from these islands, there are four more islands, each with a diameter of 600 Yojanas, located in the four directions: 13. Hyamuk, 14. Gajamuk, 15. Harimukh, and 16. Vyaghamukh.
**[Four More Islands]** Seven hundred Yojanas further from these islands, there are four more islands, each with a diameter of 700 Yojanas, located in the four directions: 17. Ashvakarna, 18. Singhakarna, 19. Akarn, and 20. Karnpravaran.
**[Four More Islands]** Eight hundred Yojanas further from these islands, there are four more islands, each with a diameter of 800 Yojanas, located in the four directions: 21. Ulkamukh, 22. Meghmukh, 23. Vidyutmukh, and 24. Amukh.
**[Four More Islands]** Nine hundred Yojanas further from these islands, there are four more islands, each with a diameter of 900 Yojanas, located in the four directions: 25. Ghanadant, 26. Lashtdant, 27. Gudhdant, and 28. Shuddhadant.
**[Total Number of Islands]** All these 28 islands are located in Jambudvipa, starting from the Jagati and extending 300 to 900 Yojanas away from the Himavan mountain. Similarly, there are 28 islands with the same names located on the projections of the Shikhari mountain, which marks the boundary of the Airvat Kshetra. Thus, there are 56 Antarvipas in total, 28 on each side.
**[The Lifespan of Antarvipaj]** The lifespan of the humans living in these Antarvipas is one Palyopam...
