Chapter 49 compares several spiritual practices. Which practice does it identify as the most important for a devotee?

According to the teachings in Chapter 49, there is a clear hierarchy of spiritual practices. The text states that penance is greater than pilgrimages, vows, sacrifices, or charity. It then clarifies that singing Hari's name is even greater than penance. However, the chapter concludes that the most supreme practice of all is "the meditation on one's own Guru." For followers of Sai Baba, this means that He is the ultimate focus. As Chapter 49 puts it, "Sai alone is the object of meditation for His devotees; Sai alone is their worship of deities. Sai alone is their secret treasure."
