What does Chapter 10 reveal about the connection between a Guru's grace and the destruction of a devotee's karma?

Chapter 10 explains that a Guru's grace has a direct and powerful effect on a devotee's karma. The text states that through the Sadguru's sight alone, the 'knots of the heart are broken' and all attachment to sense objects vanishes. Most significantly, this grace leads to the destruction of both accumulated (Sanchit) and current (Kriyaman) karmas. This process is initiated by the devotee's faith and devotion. When the Sadguru sees this purity of service, He helps the devotee overcome worldly existence (Samsara) and gives them the attainment of liberation, effectively wiping clean their karmic slate. This demonstrates that the Guru's intervention is the ultimate means to transcend the cycle of karma.
