Answer

Jain Dharma ke niyam ke anusaar, 2 Ekasana = 1 Upvas maana jaata hai.

Explanation

• Ekasana: Din mein sirf ek baar, ek hi jagah baithkar bhojan karna.
• Upvas: Poore din anna ka tyag karna.

Isliye tapasya ki ginti mein aam taur par do Ekasana ko ek Upvas ke barabar maana jaata hai.

Takeaway

Bhav se ki gayi tapasya sabse mahatvapurn hai. Sankhya ke saath-saath shuddh bhav, sanyam aur dharm-dhyan bhi zaroori hai.
