Answer

In Paryushan, whether overnight soaked almonds and walnuts are allowed depends on the rules you are personally observing and your tradition/sangh guidance.

In general Jain practice:

• Dry almonds and walnuts may be allowed in some households if they are clean, permissible, and eaten within the proper time.
• Overnight soaked nuts are often avoided by stricter observers because food kept overnight or soaked for a long time may be considered unsuitable during Paryushan observance.
• If you are doing stricter Paryushan rules, tapasya, or following temple/sangh niyams, it is better to avoid overnight soaked almonds and walnuts.

Explanation

During Paryushan, Jains usually become more careful about:

• freshness of food,
• avoiding food kept overnight,
• minimizing harm to living beings,
• simplicity and restraint in eating.

Soaked items can become questionable because soaking and keeping overnight may increase subtle life forms or fermentation concerns, depending on the duration, climate, and local practice.

Takeaway

If you want to follow Paryushan with greater strictness, avoid overnight soaked almonds and walnuts. If needed for health reasons, ask your guru, sadhu-sadhviji, or local Jain sangh for the exact rule followed in your tradition.
