Chapter 49 ranks several spiritual practices. What is the hierarchy it presents, and which practice is considered the greatest?

Chapter 49 of the Sai Satcharita establishes a distinct hierarchy among various spiritual disciplines, placing devotion to the Guru at the pinnacle. The text explains that penance is considered greater than pilgrimages, vows, sacrifices, or charity. It then states that singing Hari's name is even greater than those practices. However, the chapter concludes that "the meditation on one's own Guru is the greatest of all." For Sai's followers, it specifies that Sai alone is the object of meditation and worship. This clearly positions Guru-bhakti, or unwavering devotion and meditation on the Guru, as the supreme spiritual practice.
