Why does Chapter 11 say it's so important to worship a Guru with a physical form, like Sai Baba? Isn't it better to focus on the formless God?

Chapter 11 of the Sai Satcharitra explains that for a devotee who has a physical body, having a Guru in a physical, or Saguna, form is essential. The text argues that devotion doesn't truly manifest without meditating on this manifest form. It uses an analogy, stating that until the "bud of the mind" opens through this devotion, it won't have fragrance or attract the "bee" of spiritual experience. The chapter clarifies that while the formless (Nirguna) and the formed (Saguna) are ultimately one and the same, like melted and frozen ghee, the path for a human worshipper begins with the tangible, manifest Guru. This focus on the Saguna form is presented as a crucial step for spiritual development, as described in Chapter 11.
