Chapter 49 mentions various spiritual practices. Which practice does it say is the most important, and why?

Chapter 49 of the Sai Satcharitra makes a clear hierarchy of spiritual practices. It states that penance is greater than pilgrimages, vows, and charity, and that singing Hari's name is greater still. However, it concludes that the meditation on one's own Guru is the greatest of all. For devotees of Sai, the text emphasizes that Sai alone is their object of meditation and worship. The author finds complete personal satisfaction in the repetition of Sai's name, contemplation of His words, and meditation on His form.
