Answer

In the Sthanakvasi Jain tradition, there is no universal rule that everyone must fast “on beans” on the last day.

If you mean eating only beans / pulses on the last day before or after a fast, that is usually a local family or community practice, not a standard rule for all Sthanakvasi Jains.

Explanation

Sthanakvasi Jains commonly observe fasting and austerities such as:

• Upvas – complete fast, usually without food
• Ayambil – very simple, tasteless food once a day
• Ekasana – eating once in one sitting
• Beasana – eating twice in the day

Rules can vary depending on:

• the type of fast,
• family tradition,
• local sangh practice,
• guidance of a sadhu, sadhviji, or elder.

In Jain practice, many people avoid certain foods during tapasya, and the focus is on simplicity, restraint, non-attachment, and discipline, not on a required “beans last day” rule.

Takeaway

Sthanakvasi Jains do fast, but “beans on the last day” is not a universal Sthanakvasi rule. It is best to ask your family elder or local Sthanakvasi guru/sangh what specific practice they follow.
