What is the deeper spiritual lesson illustrated by Sai Baba's intervention in Damu Anna's business plans?

The story of Damu Anna teaches a profound lesson about faith and the protective nature of a true Guru. Chapter 25 compares Baba's seemingly restrictive advice to a mother giving a child 'bitter medicine' for its own good; the benefit is not immediately obvious but is ultimately for the child's welfare. By advising against the business, Baba was not being tempted by a share but was acting out of selfless love for His devotee's well-being. The incident demonstrates that a saint's guidance, born from omniscience, can protect devotees from calamities they cannot foresee. Damu Anna's obedience led to his salvation from financial ruin, while his friend's initial reliance on worldly intellect led to disaster, highlighting that true wisdom lies in surrendering to the Guru.
