In Jainism, prabha (pronounced "prabha") means the radiance or effulgence of a soul. It refers to the divine glow or glory that emanates from a fully enlightened being (like a Tirthankara or a kevala Jnani), not a physical light but the inner spiritual light of enlightenment.

Key points:

• Prabha signifies the luminous nature of a liberated or highly realized soul.
• It is used to describe the splendor or glory that shines from such beings.
• There is no significant difference in the meaning of prabha between Digambar and Shwetambar traditions; both understand it as the radiant nature of spiritual excellence.
• It is a spiritual concept, not a physical phenomenon.

If you’d like, I can provide a short, authentic verse or quotation that uses the term prabha in Jain scriptures.
