Besides Knowledge and Devotion, did Baba mention any other significant spiritual practice for breaking the bonds of worldly existence?

Yes, while the primary focus of the discussion is on the paths of Knowledge (Jnana) and Devotion (Bhakti), another powerful practice is mentioned. Chapter 19 notes that Sai Baba, being a 'Cloud of Mercy,' mostly explained Devotion and the chanting of the Name (Namasmaran) to his disciples as a practical means for spiritual progress. Furthermore, the text references that the Lord told Arjuna that Meditation (Dhyana) is even greater than Knowledge. It explicitly states that Sai Baba also spoke of this means—meditation—to help break the bonds of a devotee's worldly existence, indicating its high importance in his spiritual guidance alongside devotion and knowledge.
