In Jainism, yes – for a soul to attain moksha, the final moment (antim samay) must be free from passions (kashaya) like anger, pride, deceit, and greed.

But it’s important to understand this correctly and not in a fear-based way:

1. What is required at the moment of death?

For moksha to happen, the soul must be in a very pure state:

• Right faith (samyak darshan)
• Right knowledge (samyak jnan)
• Right conduct (samyak charitra) brought to its highest level
• No active passions (vitarag / kashaya‑rahit state)

If at the last moment strong passions are present, new karmas are bound and old karmas are not fully shed, so the soul does not get liberated and is reborn again.

2. Does only the last moment matter?

No. The last moment is the result of the whole life:

• A person cannot live in strong passions all life and suddenly “switch off” everything perfectly at death.
• The capacity to remain passionless at death comes from lifelong practice: vows, samayik, pratikraman, tapa, forgiveness, humility, etc.
• So: the entire life of effort + the final passionless state at death together lead to moksha.

3. Who actually attains moksha?

In this descending time-cycle (avasarpini), according to Jain doctrine:

• Only very highly evolved souls (like Tirthankars, other Kevalis, and a limited number of elevated sadhus/sadhvis) actually reach the stage where all ghati and then all aghati karmas are destroyed, and
• At the moment of death, their state is completely vitarag – then they attain moksha.

Others, even if pious and good, continue in samsar but with better future conditions and spiritual progress.

You can read a simple explanation of kashayas (passions) and how they block liberation here:

4. Practical takeaway

• Aim: Gradually reduce kashayas now – anger, ego, deceit, greed – and cultivate forgiveness, humility, simplicity, and non‑attachment.
• Result: This purifies karma and raises your spiritual level, so that in some future life you will be capable of that pure, passionless final state in which moksha becomes possible.

So:

• If one is not passionless at the moment of death, moksha is not attained in that life.
• But every sincere effort now prepares the soul for that perfect, passionless final moment in a future birth.
