Jain dharm me upvas (vrata) ki niyam sabhi sampradayo me mil jhul kar alag-alag hote hain, isliye “dal dalna ya dalna zaruri hai ya nahi” ka jawab ek niyam se nahi diya ja sakta. Phir bhi aam tor par:

• Bahut se upvas mein dal (daal/daal wale anaj) yeh grainyan nahi maane jate; lekin kuch log phir bhi dal ya legumes ko apni upvas ke dauran allow kar lete hain, ye pratha parivar/gaon/guru ki parampara par nirbhar karti hai.
• Zyada standard practice me upvas ke samay sirf phal, dudh (ya phir phalahar—phal, doodh, misri ya sugar milakar) ya nirjala upvas ki sthiti me sirf paani hota hai, yeh bhi parampara par nirbhar karta hai.
• Salt ya namak, chuna (lime) ya kuch masale bahut se sampradayo me upvas ke dauran kam ya bilkul avoid kiye jate hain.
• Digambar aur Shwetambar ke beech kuch arthik/ritual antar hote hain; isliye aapke grih-granth ya guru ke niyam sabse adhik mahatva rakhte hain.

Agar aap apni sampradaya (Digambar ya Shwetambar) ya apne guru ki instruction batayen, to main ussi parampara ke anuroop sahi, spasht upvas niyam (arth) aur agar chahiye to uchit sutra-stotra ka asli shabd aur arth bhi de sakta hoon.
