Considering Annasaheb's financial worries after retirement, why did Baba offer only vague spiritual assurances instead of providing a concrete job offer as requested?

From the perspective presented in Chapter 3, Baba's response was not vague but a profound and direct form of help that transcended a simple job. When Anna Chinchonikar pleaded for a new job for Annasaheb, Baba's reply was a divine assurance: "He will get a job, damn it! Now he should do my service; he will find happiness in the household." He further promised that Annasaheb's "plates are always full; they will never be empty as long as he lives." By directing him towards service, Baba was offering an "eternal treasure" and the removal of all calamities, which was framed as a far greater blessing and a more permanent solution to his worries than any single, temporary employment.
