Explain the role of faith and the Guru's joy as described in Chapter 27 of the Sai Satcharitra.

Chapter 27 of the Sai Satcharitra places immense importance on faith in the Guru. It states that without ultimate faith in the Guru's feet, the six passions like lust cannot be subsided, nor can the eight sattvic emotions arise. This faith is the prerequisite for spiritual progress. Furthermore, the chapter beautifully illustrates the Guru's perspective, explaining that the Guru finds supreme joy in whatever constitutes the devotee's own happiness. As the devotee turns more towards the spiritual path, the Guru feels more wonder. This highlights a reciprocal relationship where the devotee's spiritual growth becomes a source of happiness for the Sadguru.
