Answer

In many Śvetāmbara Mūrtipūjak traditions, bananas are generally avoided during Paryushan Ekāsana, especially when following stricter tap guidelines.

However, exact rules can vary by gaccha, guru-paramparā, family practice, and local sangh niyam. Since you follow Yashovijay Suri Rāyā Mūrtipūjak tradition, the best answer is to ask your guru, upāśray, or sangh authority for the exact niyam they observe.

Explanation

During Paryushan, many people make food rules stricter than ordinary Ekāsana. Fruits like bananas may be avoided because:

• They may be considered unsuitable in certain Paryushan tap practices.
• Some traditions avoid certain fruits due to ripening, storage, or subtle-life concerns.
• Different Jain families and sanghs follow different lists of allowed and not-allowed foods.

So even if banana may be eaten in some ordinary situations, it may still be avoided during Paryushan Ekāsana depending on your niyam.

Spiritual Understanding

The purpose of Ekāsana in Paryushan is not only dietary restriction, but also:

• self-control,
• simplicity,
• reduction of attachment to taste,
• and greater focus on repentance, svādhyāy, and dharma.

If there is doubt, the safer spiritual approach is to avoid the doubtful item and keep the tap as pure as possible.

Takeaway

For your Paryushan Ekāsana, do not eat bananas unless your guru or local sangh specifically permits it. When in doubt, choose a simpler permitted food and follow your tradition’s niyam with bhāv.
