Why does Chapter 11 place so much importance on meditating on Sai Baba's manifest (Saguna) form?

Chapter 11 explains that meditating on the manifest (Saguna) form of the Guru is essential for spiritual progress. The text argues that for a worshipper who has a physical body, the Guru must also be in a physical form. It states that without meditating on the manifest, devotion cannot truly manifest within a person. Furthermore, as long as this loving devotion does not occur, the 'bud of the mind' will not open or bloom. The chapter uses the analogy that an unopened bud has no fragrance and cannot attract the bee, implying that without Saguna devotion, the mind cannot experience spiritual nectar.
