Answer

In Jain fasting practice:

• 1 Upwas = fasting for one full day.
• 2 Upwas = fasting for two continuous days.
• 3 Upwas = fasting for three continuous days.
• Parna = properly ending the fast by taking food or drink according to Jain practice.

So:

• 1 Upwas then Parna is simply called Upwas.
• 2 Upwas then Parna is commonly called Bela.
• 3 Upwas then Parna is commonly called Tela.

• Tela means three consecutive Upwas.
• Parna is the respectful completion of the fast, usually done at the proper time and with suitable food or drink.

Takeaway

1 Upwas = Upwas, 2 Upwas = Bela, and 3 Upwas = Tela.
