In Jainism, "Atmaraksha" means "self-protection" or "protection of the soul." This concept emphasizes the importance of safeguarding one's own soul from karmic bondage and spiritual downfall. Atmaraksha is achieved by following the teachings of the Tirthankaras, observing the vows (vratas), practicing right faith (samyak darshan), right knowledge (samyak jnana), and right conduct (samyak charitra).

Key aspects of Atmaraksha in Jainism include:

1. Ahimsa (Non-violence): Protecting oneself from accumulating negative karma by avoiding violence in thought, word, and deed.
2. Self-discipline: Observing ethical vows such as truthfulness, non-stealing, celibacy, and non-possessiveness.
3. Meditation and Self-awareness: Engaging in practices like samayika (periodic meditation) and pratikraman (repentance and reflection) to remain aware of one's actions and intentions.
4. Detachment: Cultivating detachment from material possessions and worldly attachments to prevent spiritual downfall.
5. Study and Reflection: Regularly studying Jain scriptures and reflecting on spiritual truths.

According to Jain philosophy, true Atmaraksha leads to liberation (moksha) by destroying the accumulated karmas and preventing the influx of new karmas. Thus, the highest form of self-protection is spiritual purification and striving for ultimate liberation.
