Why does Chapter 11 emphasize the necessity of devotion to a Guru with a physical form (Saguna)?

According to Chapter 11 of the Sai Satcharitra, devotion to a manifest (Saguna) Guru is crucial because it is the most suitable path for a devotee who themselves has a physical body. The text argues that devotion cannot truly manifest without meditating on a tangible form. This meditation on the Saguna form is what allows the 'bud of the mind' to open and bloom, leading to spiritual fragrance and nectar. As the chapter states the scriptures determine, for the formless, the formless is suitable, but for one with a body, a Guru in a physical form is the essential starting point for spiritual progress.
