I’m not sure what you mean by “Dominak” in the context of Jainism.

It might be a spelling/typing issue. To help you properly, can you please clarify any of these:

• Do you mean a particular Jain story / character (like a king, acharya, or deity)?
• Is it from a specific granth (scripture/book) you have seen?
• Any language clue: Hindi / Gujarati / Sanskrit / Prakrit name?
• Can you write the word how you heard it spoken (approximate pronunciation)?

Once I know what exact word or story you are asking about, I can explain its Jain background, meaning, and lessons in simple language.
