From a Jain Dharma perspective, the incident of a slap is seen as an instance of violence (himsa), which Jainism strongly discourages. Key points:

• Ahimsa (non-violence) is the core principle. Any act that harms another’s body or peace is contrary to Jain ethics.
• Anger (krodha) and pride (man) are considered disqualifications of a seeker on the path. Letting aggression manifest in action goes against the Jain ideal of self-control.
• Forgiveness (kṣama) and compassion are virtuous responses. If harm has occurred, reconciliation, apology, and atonement are encouraged.
• Detachment from ego and attachment to truth: Jainism stresses resolving conflict through non-violent, truthful, and respectful discourse rather than aggression.

In practical terms for a Jain:

• Reflect on the intention behind the act and the impact on all involved.
• Cultivate restraint and inner forgiveness rather than retaliation.
• If harm occurred outwardly, seek peaceful, non-violent resolution and corrective conduct.

Note: Different Jain traditions (Digambar and Śvetāmbar) share the same emphasis on non-violence and self-control, though they may differ in other doctrinal details.
