From a devotee's perspective, what is the main message conveyed in Chapter 42 regarding the nature of a Sadguru and the significance of their physical departure?

For a devotee, Chapter 42 conveys several powerful messages. It reinforces the Sadguru's role as a 'Wish-fulfilling Tree' (Kalpataru) who helps one cross the 'river of worldly existence.' The chapter emphasizes that the Guru's grace turns distress into joy and opens the door to liberation. Regarding the physical departure, the text presents it not as a sorrowful end but as a significant, holy event. Chapter 42 refers to it as a 'Punya Tithi' (holy death anniversary) and notes that the death anniversary of saints is akin to the birth anniversary of gods. The meticulous recording of the date and time signifies its sacred importance, suggesting that even in leaving the body, the Sadguru's power to dissolve obstacles for those who remember his feet remains eternal.
