In Jain dharma, such events are understood mainly through the law of karma and fixed lifespan (आयुष्य कर्म / āyuṣya karma), not as “injustice” or randomness.

I’ll keep it simple and within Jain perspective.

1. “How could this happen so suddenly?”

From our side it looks “sudden” From the soul’s karmic account it is not sudden.

According to Jainism:

• The type of birth, maximum lifespan, major diseases, manner of death etc. are decided by āyuṣya karma and related karmas, which are bound long before – even in previous lives.
• We come to know about them only when they fructify (उदय में आते हैं). So it feels like:

“Yesterday she was fine, today it’s 4th‑stage cancer.” But the karmic cause was already there, just not visible.

So “sudden” means:

• Sudden to us
• But not sudden in the karmic law of the universe.

2. Her intense suffering in hospital

In Jain view, painful experiences are connected to asātā vedanīya karma (pain-producing karma) and often become a powerful time for nirjarā (shedding of karmas), if endured with patience and spiritual awareness.

What may have been happening spiritually:

• Old karmas were giving their full result through disease, pain, helplessness.
• When one remembers religion, does kshamāpanā / khamat khamna, tries to remain calm, accepts reality – it helps in purifying the soul and reducing future suffering.

Her words: > “This shouldn’t happen even to my enemies” show how intense her pain was. If she did not develop hatred towards anyone, and instead did pratikraman and kshamāpanā, that suffering could have turned into strong nirjarā for her soul.

3. Her instinct that she would die

Many times, as death comes closer:

• The āyuṣya karma is about to finish.
• The soul becomes somewhat detached from body and relations.
• A person may feel: “My time is over now.”

In Jain texts, it is accepted that some beings have pre-death awareness (especially when āyuṣya is about to end). So her feeling “I will not survive” is very much in line with Jain understanding – her lifespan karma was ending.

Her doing apology, khamat khamna at that time is very auspicious for her next journey.

4. “I just want to go home once” – yet she died on the way

This part feels very painful for family, because:

• Emotionally: it seems like such a small, harmless wish.
• Spiritually (Jain view): even whether a small wish is fulfilled or not is governed by antarāya karma (obstructing karma) and the exact moment when āyuṣya ends.

Two important points:

1. The exact moment of death is fixed by āyuṣya karma.

Not a second before, not a second after.

1. It seems her āyuṣya ended exactly when she was being taken out, so death occurred then.

We feel: “If only she had reached home, if only they had taken her earlier…” But in karmic law:

• If her lifespan was fixed to end at that very moment,
• Then any circumstance would have adjusted such that death still occurred right then, in some way.

So her not reaching home is not because anyone was cruel to her, but because the karmic clock struck its final moment.

5. “Even she must not have thought all this would happen?”

Very true. Most of us don’t.

Jain dharma teaches:

• Life is anicchādi – full of things we do not wish for.
• Body is अनित्यम् / temporary – it can change anytime.
• Any person, however “healthy”, is only apparently secure; karmas can manifest at any time.

Your relative:

• Did not plan or expect this.
• But her past karmas + present karmas created such a situation.
• Her last days, with suffering plus kshamāpanā, could be spiritually very meaningful for her soul, even if extremely painful for all of you emotionally.

6. What can family do now (Jain way)?

From Jain dharma side, helpful things are:

• Forgive her and ask forgiveness from her from the heart:

“Michchhāmi Dukkaḍaṃ” / “Khamat Khamnā” – for any pain we caused you in this life and past lives.

• Avoid blaming:

- “Why God did this?” - “Why doctors / relatives / hospital did this?” Instead see it as karmic unfolding.

• Do shubha bhāvanā for her:

- May her soul get sadgati (better state). - May she get right faith and right path in future birth.

• You may:

- Do Pooja, Swādhyāy, Pāṭh, Navkār Mantra, Pratikraman, etc., keeping her soul in mind. - Give dāna / charity with the feeling: “Let this punya support her soul’s progress.”

All this does not “buy” her destiny, but creates pure vibrations and punya that can help her and also purify your own karmas.

7. Your pain

It is fully natural to feel:

• Shock: “How so sudden?”
• Helplessness: “We couldn’t even fulfill her last wish properly.”
• Guilt: “Did we do something wrong?”

From Jain viewpoint:

• You all were nimitta (instrumental causes), not the real cause.
• The real cause was her own karmas ripening.
• You can gently accept:

“We did what we could, with the knowledge and situation we had. The final result was karmic and fixed.”

If possible, slowly turn your grief into:

• Prārthanā (prayer for her soul),
• Smaran of her good qualities,
• Resolve to live more dharmic, aware of the uncertainty of life.

In summary, within Jain dharma:

• Her sudden cancer and death were not random, but the unfolding and completion of her āyuṣya and other karmas.
• Her suffering, along with kshamāpanā and awareness of nearing death, likely helped in strong nirjarā for her soul.
• The exact moment and manner of death are fixed by karma; that is why she passed away just as she was being taken home.
• For you, the most helpful response now is forgiveness, prayer, and living with deeper spiritual awareness.
