Tilak mandir me lagana ya nahi, is par Jain dharma me koi nirdharit niyam nahi hai. Tilak parichhedan ya bhav-sparsha ki drishti se hota hai, na ki mandir ke poojan ki avashyakta.

• Jain abhishek ya puja me tilak lagana zaroori nahi hota. Mukhya drishtikon hai/shuddhikaran, bhakti, aur sadacharan par kendrit rehna.
• Agar aap kisi vyakti vishesh ya sampradaya ke anusar tilak lagate hain (jaise kuch log sandal ki paste ya kumkum se bhav-sharir par lagate hain), to wo vyakti ke vyaktigat-parampara par nirbhar karta hai. Yahan bhi tilak bahut saadha aur sammanjanak roop me hona chahiye.
• Digambar aur Shwetambar ke beech tilak sambandhi vyakhya me antar ho sakta hai, par antim roop se koi bhi universal tilak ki avashyakta Jain dharma me nahi mani jati. Apne guru ya sthaniya mandir ki pratha ko hi anusar mana jaye.

Agar aap specifically tilak ki vyavaharik prathaa ya puja ke dauran istemal par adhik jankari chahte hain, to yeh vishay aap JainKnowledge.com par mil sakta hai. You can read more here
