Answer

In common Jain tapasya counting:

1 Upvas = 2 Ekasana

So:

3 Upvas = 6 Ekasana

Explanation

An Upvas means fasting for the full day, while Ekasana means eating only once in the day, usually in one sitting.

Since one Upvas is traditionally counted as equal to two Ekasana:

• 1 Upvas = 2 Ekasana
• 2 Upvas = 4 Ekasana
• 3 Upvas = 6 Ekasana

Takeaway

3 Upvas equals 6 Ekasana in tapasya counting.
