In Jainism, the stories of the Ramayana and Mahabharata are indeed different from their Hindu versions. This is because Jainism has its own unique interpretations and retellings of these epics, which reflect Jain philosophy, values, and worldview. Here are some key reasons for the differences:

1. Non-violence (Ahimsa): Jain versions emphasize non-violence and compassion. For example, in the Jain Ramayana, Lord Rama is depicted as a non-violent hero who does not kill Ravana directly. Instead, Lakshmana kills Ravana, and Rama practices forgiveness and compassion.

2. Concept of Tirthankaras and Chakravartins: Jain literature often presents major characters from these epics as previous births (or future births) of Tirthankaras (spiritual victors) or as Chakravartins (universal monarchs), integrating them into the Jain cosmological framework.

3. Rejection of Divine Intervention: Jain texts avoid attributing supernatural miracles or divine interventions to gods. The stories are more human-centric, focusing on karma and personal responsibility rather than divine will.

4. Ethical Focus: Jain retellings stress the importance of Jain ethical principles. For instance, in the Jain Mahabharata, the emphasis is on the futility of war, the value of renunciation, and the dangers of attachment and violence.

5. Different Endings and Details: There are often significant differences in plot and character roles. For example, in the Jain Ramayana, Sita and Ravana are siblings in previous births, and the story ends with Rama renouncing the world and attaining liberation.

6. Aim of Moksha: The ultimate goal in Jain narratives is to achieve liberation (moksha) through right conduct, rather than fulfilling dharma through action, as emphasized in Hindu versions.

Examples of Jain Texts:

• Paumachariya by Vimalasuri is a well-known Jain version of the Ramayana.
• Harivamsha Purana by Jinasena and other Jain puranas recount the Mahabharata from a Jain perspective.

Summary: The Jain Ramayana and Mahabharata are different because they retell these epics through the lens of Jain values such as non-violence, renunciation, and self-realization, and adapt the characters and stories to fit Jain cosmology and ethics.
