According to Chapter 49, what is the most important spiritual practice for a devotee, and how does it compare to other religious activities?

Chapter 49 of the Sai Satcharitra establishes a clear hierarchy of spiritual endeavors, placing the Guru at the pinnacle. The text states that while penance is greater than pilgrimages, vows, or charity, and singing Hari's name is greater still, the 'meditation on one's own Guru is the greatest of all.' This teaching emphasizes that for a follower of Sai, He alone should be the object of meditation and worship. The chapter portrays Sai as the devotee's 'secret treasure,' suggesting that a focused, loving devotion to the Sadguru surpasses the merit gained from all other traditional religious practices combined.
