Answer

Raw banana wafers are generally not considered appropriate Jain āhār for Tithi and Paryushan, especially if they are fried, packaged, or prepared in advance.

Explanation

In Jain practice, during Tithi and especially Paryushan, food discipline is observed more carefully. The main concerns with raw banana wafers are:

• Raw banana is a green vegetable/fruit item, and many Jains avoid such items on Tithi and Paryushan depending on family and sect tradition.
• Wafers are often fried, and fried foods are usually avoided during serious religious observance because they increase taste-attachment.
• Packaged wafers may contain unknown ingredients such as preservatives, spices, additives, or processing agents.
• Prepared wafers may not be fresh, and during Paryushan many people follow stricter rules regarding freshness and purity of food.

Spiritual Understanding

The spirit of Tithi and Paryushan is:

• simplicity in food,
• control over taste,
• carefulness in ahimsa,
• and reduction of indulgence.

So even if something may appear technically vegetarian, it may still not match the higher discipline expected during Paryushan.

Takeaway

For Paryushan and Tithi, it is better to avoid raw banana wafers. Prefer simple, fresh, sattvik Jain food according to your family, temple, or Guru’s maryādā.
