In Jain philosophy, “Heya” (हेय) means:

> That which is to be given up / avoided / abandoned.

More clearly:

• Heya = things we should leave, stop, or avoid because they keep us in bondage (saṁsār).
• Examples of heya in Jainism:

- Pāp (sinful activities) - Āsrav (influx of karma into the soul) - Bandh (bondage of karma with the soul)

Often it is explained together with two other words:

• Jñeya – what is to be known (like jīva and ajīva)
• Heya – what is to be avoided (pāp, āśrav, bandha, etc.)
• Upādeya – what is to be adopted/practised (puṇya, saṁvar, nirjarā, mokṣa)

Both Digambar and Shvetambar traditions use heya in this same basic sense: “that which is spiritually harmful and therefore must be abandoned.”
