Jainism ke shastron ke anusar, dev (deities) ki sankhya anant (infinite) hai, lekin jinendra bhagwan ke samay mein chaar mukhya dev-lok (heavenly abodes) bataye gaye hain:

1. Vyantar Dev
2. Jyotishka Dev
3. Vaimanika Dev
4. Bhuvanpati Dev

In sabhi lokon mein anek prakaar ke dev aur unke parivaar, purvajanm ke karmon ke anusaar, janm lete hain. Pratyek dev-lok mein bhi anek tarah ke dev hote hain jaise Indra, Samanik, Trayastrimsa, etc.

Is prakar Jain shastron ke anusar devon ki koi nishchit ya seemit sankhya nahi hai; ve anant hain.
