Why does Chapter 11 stress the importance of a Guru having a physical form?

According to Chapter 11 of the Sai Satcharitra, it is crucial for a devotee to worship a Guru in a physical form because the worshipper themselves has a form. The text argues that devotion cannot manifest without meditating on the Saguna, or manifest, form. It uses the metaphor of a flower, explaining that until the bud of the mind opens through loving devotion, it has no fragrance and cannot attract the bee of divine experience. The scriptures, as cited in this chapter, determine that for a being with form, a formless object of worship is not suitable.
