Neminath (Aristanemi), the 22nd Tirthankara, is celebrated for immense spiritual strength (bal) and supreme renunciation.

• The Jain tradition says his outer strength was extraordinary—even "far greater than Vasudeva and a Chakravarti"—but his power was directed to spiritual victory: conquering the inner enemies (kashays) like anger, pride, deceit, and greed, to attain kevala jnana (omniscience). This is the strength that makes him an Arihant and a guide to liberation. ( jainknowledge.com)
• Legends recount feats of strength in his youth, such as handling martial prowess and symbolic displays (for example, equipping conch and discus), but in Jain teaching these are demonstrations of his sovereignty and self-control used for dharma, not violence. The core message is that his true power lies in detachment and self-mastery, not in harming others. ( jainknowledge.com)
• In Digambara and Śvetāmbara traditions, the essential idea remains the same: Neminath’s strength is spiritual mastery and compassion leading to renunciation and moksha. Some narrative details may vary between texts, but the reverence for his invincible spiritual strength is shared. ( jainknowledge.com)
