According to Chapter 11, why is devotion to a manifest (Saguna) Guru considered important for a spiritual seeker?

Chapter 11 of the Shri Sai Satcharitra strongly advocates for the importance of devotion to a Saguna, or manifest, Guru. It argues that as long as a worshipper has a physical body, the Guru must also be in a physical form for a tangible connection. The text posits that without meditating on this manifest form, true devotion can never arise. This devotion is essential because it allows for a personal relationship where one can place their head at the Guru's feet, exchange words of love, and perform worship with offerings. The chapter explains that this initial love for the Saguna form is the most accessible path, and once that love is firmly established, the deeper realization of the formless (Nirguna) will naturally follow.
