Here are the main ways (karma-causing actions) that Jain scriptures say bind the soul and can lead to Narak (hell) in the afterlife:

• Himsā (violence) and harming living beings: killing, torturing, or injuring any living creature.
• Asteya (stealing): taking what is not freely given or unjustly depriving others.
• Satya (falsehood): lying or deceitful speech; misrepresenting the truth.
• Brahmacharya or sexual misconduct: for laypeople, improper sexual behavior; for monks/nuns, complete celibacy.
• Aparigraha (unnecessary attachment/greed): excessive desire for possessions, possessions, or sensual pleasures.

In Jainism, these external actions are fueled by inner passions (kasāya) that bind karma:

• Krodha (anger)
• Mana (pride)
• Maya/Mada (deceit or delusion)
• Lobha (greed)
• Rāga/attachment (pull toward sensual pleasures)

These inner faults can lead to serious karmic bondage, which, depending on the balance of merits and demerits, may result in rebirth in Narak for varying durations.

Ways often taught to avoid Narak and purify the soul:

• Practice non-violence (ahimsa) in thought, word, and deed.
• Speak truthfully and avoid deceit (satya).
• Do not steal; respect others’ property (asteya).
• Observe proper conduct regarding sexuality (for householders, ahimsa in relations; for renunciants, complete brahmacharya).
• Cultivate detachment from possessions and desires (aparigraha) and reduce attachment to sensual pleasures.
• Speak and act with right faith, right knowledge, and right conduct (the Jain path of the three jewels).

If you’d like, I can share a short, authentic sutra or stotra in Sanskrit or Prakrit with its Jain-anubhashā and brief arth (meaning) that relates to restraint from these karmas.
