Describe the daily worship routine of the Tarkhad son and how his father, Babasaheb, attempted to continue it.

As told in Chapter 9, the son's devout daily routine began after his morning bath. He would perform worship of Sai's photograph with his body, speech, and mind, concluding with a Naivedya offering, without which he would not eat. When his son left for Shirdi, Babasaheb Tarkhad took over this sacred duty. He began his own worship by praying to Sai's image that his service would be as good as his son's and that no mistakes would occur. He established a rule of offering a piece of sugar candy as Naivedya every day, a practice he followed until the day he unfortunately forgot due to being preoccupied with business.
