According to Chapter 10, what effect does devotion to the Sadguru have on a person's karma and worldly attachments?

According to Chapter 10, sincere devotion to the Sadguru has a profound and transformative effect on a person's karma and worldly attachments. The text states that by the Sadguru's mere sight, "the knots of the heart are broken" and "all attachment to sense objects vanishes." Most significantly, Chapter 10 explains that for a devoted follower, both accumulated (Sanchit) and current (Kriyaman) karmas are destroyed. This cleansing of karmic debt is presented as a crucial step towards liberation from the worldly existence (Samsara), which the Guru helps one cross, ultimately untying the knot of birth and death.
