Answer

In Jain practice, 1 Upwas is commonly considered equal to 12 Vanditu Sajaya.

Explanation

This means that if someone cannot do 1 Upwas due to health or other valid reasons, they may be advised to do 12 Vanditu Sajaya as an alternative form of austerity or repentance, depending on the guidance of their Guru or local tradition.

Takeaway

For exact practice, especially during Pratikraman, Tapasya, or Prayaschit, it is best to follow the guidance of your Guru Bhagwant or your Jain tradition.
