In Jain tradition, the life stories of the Tirthankaras are full of miraculous signs and events, but these signs are not the goal of a spiritual path. They appear in the hagiographies (Purāṇas and Jain scriptures) to illustrate the divine nature and extraordinary destiny of a Tirthankara, not to prescribe practice for lay or monk followers.

Key points:

• What is central: Right faith (samyak-darśana), right knowledge (samyak-jnana), and right conduct (samyak-charitra). These are the core path for a Jain practitioner, whether a layperson or monk.
• Signs and miracles: Often described in the birth, life, and renunciation of a Tirthankara to show his or her special status. Examples include auspicious omens at birth or episodes of incredible events. These events are part of mythic literature and tradition, not required practices for devotees.
• Differences between Digambara and Śvetāmbara:

- Śvetāmbara accounts tend to include more explicit birth signs and miracle episodes in the life narratives of many Tirthankaras. - Digambara accounts emphasize renunciation, austerities, and kevalajñāna (omniscience) with less focus on birth signs and marvels.

• Practical takeaway: Treat the signs as literary or devotional contexts that point to the goal—liberation (moksha) through right conduct and realization. Do not confuse miraculous signs with the actual method of spiritual progress.

If you’d like, I can share a specific teaching or a sutra/stotra that discusses a Tirthankara’s life or signs, and explain its arth (meaning) from authentic Jain sources. I can also point you to a JainKnowledge.com page that fits your interest.
