You mean Paryushan (Shwetambar) / Das‑Lakshan (Digambar).

Short answer: Yes, fruits are allowed during Paryushan when you are eating—unless you have taken a specific fast or vow that excludes them.

Details:

• If you are fasting (Upvas, Attham, Atthai, Masakshaman): no eating at all, so no fruits.
• Ekasana/Beasana (one or two sittings): fruits may be taken in that sitting, before sunset, with boiled water only in daylight.
• Chauvihar (after-sunset restraint): no food after sunset, so no fruits after sunset.
• Ayambil: only one very plain meal without spices, oil, milk/curd, sweets, green vegetables, etc. Fruits are not taken in Ayambil.
• General Paryushan restraint: avoid root vegetables (kand‑mool). Fruits are not roots, so generally permitted.
• Tradition note:

- Shwetambar: many observe “no green vegetables” during the 8 days; fruits are usually fine within your pachchakkhan (vow). - Digambar (Das‑Lakshan): simple sattvik food on permitted days; fruits are generally fine unless your personal vow restricts them.

Always follow the pachchakkhan you have taken from your guru or as per your family’s tradition.
