Yes, you can eat makhana (fox nuts / lotus seeds) in Jainism.

From a Jain point of view:

• Makhana is a seed, not a root or underground vegetable.
• It is therefore generally bhakshya (permissible) for Jain householders in both Śvetāmbara and Digambar traditions. ( jainknowledge.com)

However, keep these points in mind:

1. Daily Jain diet (normal days)

- Makhana is allowed. - Roast it simply (dry-roast or with a little ghee/oil if that is your family practice). - Avoid mixing with onion, garlic, or very spicy/fermented items.

1. Paryushan / Das Lakshan & stricter vows

- Many Jains still allow plain, well‑cleaned makhana along with other dry nuts/seeds during Paryushan, if local maryada permits. ( jainknowledge.com) - Some follow extra‑strict rules and avoid items grown or stored in water during this period, so a few families may stop makhana then. ( jainknowledge.com) - Always follow your family tradition, local sangh rules, and your guru’s guidance.

1. Not abhakshya

- Makhana is not counted in the main abhakshya list (like meat, alcohol, honey, root vegetables, etc.). ( jainknowledge.com)

So in simple words:

• Normal days: Yes, you can eat makhana.
• Paryushan / special fasts: Usually allowed if kept plain and your local maryada agrees; if in doubt, avoid or ask your guru.
