In Jain tradition, approaching a Jain sadhu (monk) or sadhvi (nun) for guidance, pravachan (spiritual discourse), or blessings is a respected practice. Here’s how you might respectfully request this:

1. For Guidance or Pravachan: You may say with humility: "Maharaj Saheb/Mataji, कृपया हमारे जीवन मार्गदर्शन हेतु प्रवचन दीजिए। हम आपके आशीर्वचन सुनना चाहते हैं।" (“Respected Sadhu/Sadhvi, kindly give us a spiritual discourse for the guidance of our lives. We wish to listen to your words of wisdom.”)

2. For Blessings: Jain monks and nuns do not give blessings in the conventional sense, as they themselves strive for detachment and equanimity. However, laypeople may still seek their 'ashirvad' (blessings) in the form of spiritual encouragement: "Maharaj Saheb/Mataji, कृपया हमें धर्ममार्ग पर चलने की प्रेरणा दें।" (“Respected Sadhu/Sadhvi, please inspire us to walk on the path of dharma.”)

Important Jain Etiquette:

• Always approach with folded hands (Namaskar Mudra).
• Address them with utmost respect: “Maharaj Saheb,” “Mataji,” or “Gurudev.”
• Avoid touching them or offering food directly (due to their vows).

Remember: Jain monks and nuns bless by saying phrases like:

• “धर्म लाभ” (Dharma Laabh – may you gain religious merit)
• “सम्यक्त्व लाभ” (Samyaktva Laabh – may you attain right faith)
• “मंगल हो” (Mangala Ho – may there be auspiciousness)

Approaching with humility and a pure heart is considered the right way in Jain culture.
