Can you explain the story of Haribhau Karnik and the lesson about trusting one's initial good intentions?

The story of Haribhau Karnik from Dahanu, found in Chapter 33, is a powerful lesson in faith. After completing his worship in Shirdi and receiving permission to leave, Karnik felt a sudden urge to go back and offer Baba one more rupee. He suppressed this thought. Later, in Nashik, the saint Narsing Maharaj unexpectedly grabbed his wrist and demanded, 'Give my Rupee.' Karnik was amazed and realized Sai himself was collecting the offering through another form. The moral, as explained in the text, is that the initial good impulse that arises in the mind is precious and should be nurtured, as it is beneficial and represents a divine connection.
