Answer

The symbol shown in the centre for a Tirthankar is called a Lanchhan or Chinha.

Explanation

In Jain tradition, each of the 24 Tirthankars has a specific identifying symbol called a Lanchhan. Since Tirthankar idols often look peaceful and similar in posture, the Lanchhan helps devotees identify which Tirthankar the idol represents.

For example:

• Rishabhdev Bhagwan — Bull
• Ajitnath Bhagwan — Elephant
• Parshvanath Bhagwan — Snake hood
• Mahavir Swami Bhagwan — Lion

Spiritual Understanding

The Lanchhan is not worshipped separately as the main object. It helps identify the Tirthankar and supports devotion, remembrance, and reverence toward their qualities of infinite knowledge, faith, conduct, and compassion.

Takeaway

The symbol in the centre associated with a Tirthankar is called the Lanchhan, the identifying mark of that Tirthankar.
