Lanchan ka matlab hai ek vishesh chihn ya pratima jo har Tirthankar ke saath joda jata hai. Ye chihn ya symbol un Tirthankar ki pehchaan ke liye hota hai, taaki bhakt aasani se us Tirthankar ko pehchan sake aur unki upasana kar sake.

Thirthankar ke sharir par jo chinh (marks) ya chihn aap idol ya murtiyon me dekhte hain, wo lanchhan hi hai. In chinhon ko murtiyon par dikhaya jata hai taaki:

• har Tirthankar ki alag pehchan ho.
• bhaktono ko shreshth aadi atma aur jina ki kripa ki yaad dila sake.
• pratek Tirthankar ki jain sadhana, virtiyon aur sthiti ko darshaya ja sake.

Kuch baatein spasht rakhne layak:

• Lanchhan dharmik pehchan hai, yeh vyakti ki real zindagi se juda hua sharirik nishan nahi hota.
• Digambar aur Śvetāmbara traditions me kuch symbols ki pehchan ya chinhon ki soochi alag ho sakti hai; dono mein hi har Tirthankar ko ek vishesh symbol mila hota hai, lekin kuch vyavahar ya chihn thoda alag dikhaye ja sakte hain.

Agar aap chahen to main specific Tirthankar ke lanchhan ki list (duroop ya symbol) Digambar aur Śvetāmbara ke anusar samjha sakta hoon.
