Jainism ke anusar, sunset (surya ast) ke baad paani peena ya bhojan karna "Ratri-bhojan" kehlata hai, jo ki ek mahattvapurna pachhkhaan (vrat) hai. Jo shravak ya shravika surya ast ke baad paani ya bhojan nahi lete, ve "Ratri-bhojan tyag" ka pachhkhaan rakhte hain.

Agar kisi din sunset ke baad paani pe liya, toh us din ka "Ratri-bhojan tyag" pachhkhaan toot jaata hai. Isse us din ki is vrat ki loyalty (palana) nahi rahi. Isliye, jo log "Ekashan", "Beashan", ya "Chauvihar" jaise vrat rakhte hain, unke liye bhi sunset ke baad paani peena vrat ki shuddhata ko bhang karta hai.

Saaransh: Sunset ke baad paani peena "Ratri-bhojan tyag" pachhkhaan ki loyalty ko todta hai.
