Choviyaaro upvas pachkan is a Jain fasting practice. Here is a simple, authentic snapshot in line with Jain Dharma:

• What upvas means: Upvas (upavās) is a period of self-discipline where a devotee minimizes external enjoyments and ascends toward ahimsa (non-violence), truth, and detachment. The core aim is spiritual upliftment, not just dietary rules.

• Typical forms of upvas:

- Aahaar-vicharan (limited meals): One may eat only a few small, strict meals or skip meals on certain days. - Nirjala or partial fasts: Some observe water only or only boiled water, while others may permit tea or dairy in very restricted forms depending on tradition and personal vow. - Day-long or multi-day fasts: Observed on specific holy days or as part of a vrata (vow), with strict discipline about activities, sleep, and speech.

• How it is practiced:

- Avoiding grains, roots, or certain foods, depending on the vow taken. - Staying away from harm to living beings, practicing fasting with mindful conduct (samayik) and reflection on non-violence. - Maintaining cleanliness, gentle speech, and restraining senses to deepen inner focus.

• Differences between Digambar and Shwetambar:

- Both traditions emphasize self-control and ahimsa; the exact disciplines (which foods are avoided, how strictly one fasts, and the rules around meals) can vary in minor details. - The spirit and aim of upvas remain the same: purification of the soul and detachment from worldly pleasures.

• Important cautions:

- Fasting should be undertaken with proper guidance, especially if you have health concerns. Jain practices prioritize life and health; modify fasts if needed for well-being.

If you’d like, I can provide:

• The exact Sanskrit/Prakritic terminology for the specific upvas you’re referring to, along with its traditional arth (meaning) as per Jain scriptures.
• A short, traditional sutra/stotra text related to upvas, with a clear Jain interpretation in both Digambar and Shwetambar contexts.

(If you meant a particular text, mudra, or set of days labeled “Choviyaaro,” tell me and I’ll map it precisely to the relevant Jain tradition and give you exact wording and meanings.)
