Good observation. In Jainism, “jealousy” (īrṣyā / irshyā) is definitely considered a paap-bhāv (sinful mental state), but it is not listed separately in the 18 Pāapsthān because:

1. It is included inside “Dveṣh” (hatred/aversion)

- One common definition of dveṣh is: inner burning, dislike, intolerance of others’ happiness or success. - Jealousy is exactly this: “I cannot tolerate that the other person is happy / progressing.” - So, in Jain philosophy, jealousy is treated as a part or form of dveṣh, not as an independent 19th category.

1. 18 Pāapsthān are “roots” or “sources” of sins, not every single emotion-word

- The list of 18 is a group of main headings under which many detailed mental states are covered. - For example: - Rāga (attachment) covers liking, craving, partiality, etc. - Dveṣh covers hatred, angerful aversion, jealousy, revengeful feelings, etc. - If every sub‑emotion were listed separately, the list would become extremely long. So the āgamas group them under broader roots.

1. Jealousy is also connected with Mān (ego) and Lobh (greed)

- We often feel jealous because: - “Why does he have more respect / wealth / success than me?” → Mān (pride, superiority/ inferiority feeling). - “I also want what he has, I can’t bear him having it” → Lobh (greed). - So jealousy usually arises out of a combination of Mān + Lobh + Dveṣh. - These three are already clearly included in the 18 Pāapsthān.

1. Scriptures focus on the basic kashāyas and root wrong attitudes

- Jain Darshan says the main enemies are Krodh, Mān, Māyā, Lobh, Rāga, Dveṣh, Mithyātva, etc. - Jealousy is seen as a prakār (type) of these, especially of Dveṣh and Mān, so it does not need a separate slot.

So, jealousy is paap according to Jain Dharma, but it is counted inside “Dveṣh” (and related kashāyas) within the 18 Pāapsthān, not as a separate 19th name.
