Seedha, paramparik niyam:

• Raat (suryaast ke baad) paani nahi.
• Subah paani sirf suryoday ke baad. Uttam reeti: Navkarsi ke baad — yani suryoday ke lag‑bhag 48 minute baad hi peeyen.
• Sirf ubla hua, chhanna hua saaf paani (koee barf/maza‑darh peey padarth nahi).
• Din ke samay hi paani; suryaast hote hi bandh.

Vrat ke anusar

• Upvaas, Ekasana, Ayambil: din me hi thoda‑thoda ubla paani, Navkarsi ke baad; raat me bilkul nahi.
• Chauvihar/ Tivihar rakhne par: agle din bhi wahi niyam — paani Navkarsi ke baad hi.

Parampara ka antar

• Shvetambar aur Digambar dono me mool niyam ek hi: paani din me, raat me nahi. Kuchh Digambar maryada me kuchh vraton me dopahar ke baad bhi paani rok dete hain. Apne guru/saá¹…gh dwara bataye samay ka hi paalan karein.

Swasthya

• Aapat‑sthitiyon me jeev‑rakshan pratham hai; avashyak ho to maryada ke saath chhoot di jaati hai.

Vistaar aur pachkhan ke liye:

• Navkarsi (48 minute baad) samay aur reet:
• Paryushan/din me paani kab se kab tak:
• Upvaas todne/pehle peene ka sahi samay:
