In Jain dharma, Mahāvideh Kṣetra is indeed possible only through high punya and the right karmic causes. If someone feels “my punya is very less,” then the correct understanding is:

• Do not depend only on present feeling.
• Punya can be increased through:

- dāna, - sēvā, - samyak darshan, - samyak chāritra, - japa, bhakti, and vinaya, - and above all ahimsā, satya, and aparigraha.

In Jain teaching, birth in Mahāvideh Kṣetra is not by wish alone. It comes when the soul has the right karma, right bhāva, and strong punya. So if punya is presently weak, the path is to build noble karma now rather than to worry.

Also, the deepest point is this:

• Real progress is not only reaching Mahāvideh Kṣetra
• but reducing karma and moving toward moksha

So the proper attitude is:

“My punya may be less now, but by pure conduct, devotion, and right effort, it can increase.”

If you wish, I can explain this in simple Jain terms with the difference between punya, punya-bandh, and Mahāvideh gati.
