[154] The *Brihatkalpa Sutra* commentary, in the first verse of the *Prajnapana Sutra* on the twenty-five *Aryadesha* of this *Bharat Kshetra*, mentions their names as follows: 1. Magadha, 2. Anga, 3. Bang, 4. Kalinga, 5. Kashi, 6. Kaushala, 7. Kuru, 8. Saurya, 9. Panchala, 10. Jangala, 11. Saurashtra, 12. Videha, 13. Vatsa, 14. Sandibba, 15. Malaya, 16. Vachcha, 17. Acchha, 18. Dasharna, 19. Chedi, 20. Sindhu-Sauvira, 21. Surasena, 22. Bhrigu, 23. Kunala, 24. Kotivarsha, 25. Ladha and Kekaya.
The *Prakrut Sutra* defines their boundaries as follows: In the east, from Angadesha (whose capital was Champa) to Magadhadesha (whose capital was Rajagriha). In the south, to Vatsadesha (whose capital was Kosambi). In the west, to Sthuna desha. In the north, to Kunala desha (whose capital was Sravasti). This is the prescribed area for *sadhu-sadhvi* to travel.
The reason for this is that within these four boundaries, the glories of the *Tirthankaras* are manifested, including their birth, liberation, etc. It is here that the *Sarvajña-Sarvadarshi* *Tirthankaras* and other great beings, who generate knowledge and vision, preach the Dharma. It is here that the *bhavya jiva* attain enlightenment and it is here that they dispel their doubts by listening to the Dharma from the *Jinavaras*. Additionally, *sadhu-sadhvi* receive *bhakti-paan* and *upadhi* easily here, and the *shravaka* people or others here are knowledgeable about the conduct and thoughts of the *sadhu-sadhvi*. Therefore, they should only travel within these *Aryakshetra*.
The *Sutra* clearly states: "This is the *Arya Kshetra* and this is the prescribed area for travel. It is not permissible to travel outside of this." This means that this is the eternal *Aryakshetra*.
Perhaps, due to the good influence of a king or someone else, the people of a non-*Aryakshetra* may become *Arya* in nature, but this change would be temporary. Similarly, in an *Aryakshetra*, there may be a temporary change where the people become non-*Arya* in nature. This is why the final section states: "Even though there are boundaries of the *Kshetra* and boundaries of the *Kalpa*, one should travel wherever the development of *samyama* qualities occurs." Because sometimes, in a non-*Aryakshetra*, one's *samyama* qualities may increase and the *Jinasasana* may be influenced, and sometimes, in an *Aryakshetra*, one's *samyama* qualities may decrease. Therefore, the *Sutra* mentions the boundaries of the *Kshetra* and specifically prescribes travel with the goal of increasing *samyama*.
The *Bhashya* and *Tika* explain that currently, due to the influence and efforts of kings, *sadhu-sadhvi* have started traveling in non-*Aryakshetra* as well. In *Aryakshetra* too, where there are long routes, dense forests, which take many days to cross, traveling in those areas is prohibited in *Acha. Shru. 2, A. 3* and the faults of traveling in those areas are also explained. Therefore, *sadhu-sadhvi* should not go to such divisions of the *Aryakshetra*.
