Answer

In Jain tradition, the kesar tilak is not mainly connected to one specific person who “sacrificed his life.” It is generally applied as a symbol of devotion, purity, auspiciousness, and reverence toward the Tirthankar, Guru, or sacred worship.

Explanation

In Jain puja, kesar is considered sacred and pure. Applying kesar tilak usually represents:

• Bhakti — devotion toward Arihant Bhagwan
• Shuddhata — inner purity
• Mangal — auspicious feeling
• Vinay — humility and respect

If you are asking about a particular story where someone gave their life in connection with kesar tilak, I would need the exact name, place, or tradition you are referring to.

Takeaway

Kesar tilak in Jain Dharma is primarily a devotional and auspicious symbol, not universally tied to one specific martyr or sacrifice story.
