Bhagwan ke mandir (Jain temple) mein diya (lal jots) isliye hota hai ki:

• Roshan (prakash) ka sign, andhkaar ko door karna: diya roshni ki tarah hamari antar-atma ki jnana, shuddhi aur vivek ko jagata hai.
• Shuddhata aur tapas ki pratima: jalne wala diya hamari tapas aur self-discipline ki nishani manta hai.
• Samman aur shraddha ka pratik: mandir mein arihaant, tirthankar ya sadhu-sant ki pooja ke samay diya jalana shraddha jaahir karne ka ek tarika hai.
• Shanti aur vyavastha: mandir me halka-fulka prakash se sthaan par shanti aur sukun ka anubhav hota hai.

Jain dharma mein pooja ka mool uddeshya samayik dhyan (antar-dhyana) aur aradhya tirthankaron ki gunon ki soch ko badhava dena hota hai, na ki koi vastu-pooja ya bhakti alone. Digambar aur Shwetambar dono prathna ke liye diya jala sakte hain, lekin dono sangh mein iski mahatva ki samajh lagbhag ek jaise hi hoti hai.
