The text mentions Cholkar's difficulty in crossing the 'threshold-ghat.' How does this concept relate to the delay in his vow, and what broader spiritual lesson did Baba impart following this incident?

In Chapter 15, the 'threshold-ghat' is a metaphor for the immense challenge of managing household expenses for a worldly person, which can be as difficult as crossing a vast mountain cliff. This directly relates to the delay in Cholkar's vow, as his financial struggles prevented him from affording the journey to Shirdi right away. After revealing His knowledge of Cholkar's secret sacrifice with the sugared tea, Baba imparted a profound spiritual lesson about His omnipresence. He explained, 'My home is in your heart; I am your inner self.' Baba taught that physical distance is irrelevant, as He is with His devotees always, even if they are 'beyond the seven seas.' The ultimate lesson was that He resides in the inner self of all beings and that one should bow to this inner divinity, recognizing the unity between the self and Baba.
