Based on Chapter 33, what is the range of ailments and troubles that can be addressed by using Sai Baba's Udi?

Chapter 33 of the Shri Sai Satcharita illustrates that Udi can address a wide spectrum of issues, from general life obstacles to specific physical ailments. The text promises the 'removal of obstacles is immediate' for the faithful. It also explicitly mentions its power to cause the 'complete eradication of bone-wounds' and the 'cure of boils, cure of glandular fever.' Beyond this list, the chapter provides narrative evidence of its efficacy, citing the healing of a girl so weak she couldn't walk and the curing of severe, prolonged insomnia in two separate cases, showcasing the broad and potent healing power attributed to the sacred ash.
