What does Chapter 10 say about the power of remembering the Guru and the effect of his service on a devotee's life and karma?

Chapter 10 emphasizes that simply remembering the Guru with a loving heart is the 'best of all means (Sadhana),' capable of untying the knot of birth and death. It states that where the service of the Sadguru is pure, the worldly existence (Samsara) is completely destroyed without any need for intellectual struggle. For the devoted, the Sadguru helps them overcome physical, mental, and divine miseries. Furthermore, the chapter notes that by the Guru's sight, a devotee's accumulated (Sanchit) and current (Kriyaman) karmas are destroyed, attachments vanish, and they receive the effortless attainment of liberation (Moksha).
