Answer

“Nardev Sagar Surishwar Ji Maharaj” appears to refer to a Jain Acharya/Maharaj Saheb, but I do not have enough clearly established information to give a reliable biography or details.

Sorry, I can only provide information that is clearly established within Jain tradition.

Clarification

If you want, you can ask with more context, such as:

• His full name with correct spelling
• Gaccha/sampraday
• Guru-parampara
• Place or era associated with him
• Whether you want biography, pravachan, guru-vandana, or historical details
