How does Chapter 49 rank various spiritual activities in order of importance?

Chapter 49 provides a clear hierarchy of spiritual practices. It states that the meditation on one's own Guru is the greatest of all. This practice is explicitly ranked as being superior to singing Hari's name. Singing Hari's name, in turn, is considered greater than penance. Finally, penance is described as being greater than other common religious observances such as pilgrimages, vows, sacrifices, or charity. Therefore, this chapter firmly establishes that for a devotee, the most supreme and valuable spiritual discipline is the focused meditation upon their Sadguru, who for the author is Sai Baba.
