According to this chapter, what is the Sadguru's role in dealing with a devotee's karma and attachments?

Chapter 10 of the Shri Sai Satcharitra describes a profound role for the Sadguru in a devotee's spiritual purification. It states that by the Guru's mere sight, the "knots of the heart are broken," and all attachment to sense objects vanishes. Furthermore, the text makes a powerful claim about karma, asserting that both accumulated (Sanchit) and current (Kriyaman) karmas are destroyed through the Guru's grace. This process is presented as a direct result of the Sadguru's power, which ultimately helps the devotee cross the worldly ocean and attain liberation (Moksha) characterized by bliss, as detailed in Chapter 10.
