佛頂尊勝陀羅尼經教跡義記 1.63

1.63

述曰：第五示所生界。言贍部洲者，依《俱舍論》云：「在須彌山南，度山有香醉山，香醉山南有大雪山，雪山北香山南有無熱惱池，池側有林曰贍部。其樹高大。其菓甘美。依此林故故名贍部洲。」《樓炭經》云：「須彌山南名南閻浮提，山西名西瞿耶尼，山北名北欝單越，山東名東弗婆提。言南閻浮提者，廣長二十八萬里，上闊下狹，有六萬山陵五百大河，人壽一百二十歲，持五戒者即得生人中，其身長三肘或四肘，初時長命，劫末極短下至十歲。言西瞿耶尼者，廣長三十二萬里，形如正圓，受命二百五十歲，修下下品十善得生其中，身長十六肘。言欝單越者，廣長四十萬里，地正方，壽命千歲，修下上品十善得生其中，身長三十三肘。言東弗婆提者，廣長三十六萬里，其地如半月形，壽命五百歲，修下中品十善得生其中，身長八肘。」此贍部洲者，即是四天下之一數也。

The commentary says: Fifth, pointing out the realm of rebirth. Regarding Jambudvīpa, according to the Abhidharmakośa-bhāṣya: 'To the south of Mount Sumeru, crossing the mountain, there is the Gandhamādana Mountain; to the south of the Gandhamādana Mountain is the great Himālaya Mountain; north of the Himālaya Mountain and south of the Gandhamādana Mountain is Lake Anavatapta. Beside the lake there is a grove called Jambu. Its trees are tall and large, and its fruits are sweet and delicious. Because of this grove, it is called Jambudvīpa.' The Loutan jing states: 'To the south of Mount Sumeru is called South Jambudvīpa; to the west of the mountain is called West Godānīya; to the north of the mountain is called North Uttarakuru; to the east of the mountain is called East Pūrvavideha. South Jambudvīpa is 280,000 li wide and long, broad above and narrow below, with 60,000 mountains and 500 great rivers. The human lifespan is 120 years; those who maintain the five precepts obtain rebirth among humans. Their bodies are three or four cubits tall; at first their lifespans were long, but at the end of the kalpa they become extremely short, down to ten years. West Godānīya is 320,000 li wide and long, shaped like a complete circle. Lifespan is 250 years; those who cultivate the lowest of the low grade of the ten virtuous actions obtain rebirth therein, and their bodies are sixteen cubits tall. Uttarakuru is 400,000 li wide and long, its land square. Lifespan is 1,000 years; those who cultivate the lowest of the high grade of the ten virtuous actions obtain rebirth therein, and their bodies are thirty-three cubits tall. East Pūrvavideha is 360,000 li wide and long, its land shaped like a half-moon. Lifespan is 500 years; those who cultivate the lowest of the middle grade of the ten virtuous actions obtain rebirth therein, and their bodies are eight cubits tall.' This Jambudvīpa is one among the four continents under heaven.
