Why does Chapter 11 of the Satcharitra emphasize worshiping a Guru with a physical form, or a 'Saguna' Guru?

Chapter 11 explains that devotion to a 'Saguna' or manifest Guru is essential for a devotee who themselves has a physical form. The text makes a direct connection, stating that "as long as the worshipper has a form (body), the Guru must also be in a physical form." It argues that without meditating on this manifest form, true loving devotion cannot arise, and the mind cannot spiritually blossom. As described in Chapter 11, this is a determination of the scriptures, suggesting that for the formless, the formless is suitable, but for embodied beings, an embodied Guru is the necessary path to spiritual experience and opening the 'bud of the mind'.
