Agle din peene ka pani peene ki koi vishesh tithi ya din Jain dharm me nahi hai. Rozana jab pyaas lage ya needs ho, tab pani piya jata hai.

Sirf kuch vishesh vrat ya upvas ke din pani pine par nirodh ya bahut kam kiya jata hai:

• Nirjala upvas: kuch log is vrat me ek din ya adhik din bina khana-bina pani ke rahte hain (yaani pani bhi nahi pehte). Is halat me us din pani nahi peete.
• Anya upvas/vrats: bahut se vraton me log din bhar ya kuch ghanto ke liye bhojan/pani ki sima rakhte hain, lekin aam dinon me log pani peete hain.

Agar aapka sawal kisi khaas vrat ya samay se juda hai, to us vrat ki shuddh aur digambar/shwetambar ki parampara ke hisaab se alag vyakhya ho sakti hai. Par aam tor par agle din ya kisi nishchit tithi ke hisaab se pani peene ki koi niyamit pratice nahi hai.
