According to the Satcharitra, how can one overcome life's struggles and attain liberation through the Guru?

Chapter 10 of the Shri Sai Satcharitra teaches that the most effective path to overcoming struggles is devotion to the Sadguru. It states that by placing faith in the Guru's feet, He can alter one's destiny, poetically described as 'striking a nail over the lines of destiny.' The chapter portrays the Guru as a boatman who safely guides devotees across the 'ocean of existence.' Through the Guru's grace, the three types of miseries are overcome, attachments to sense objects vanish, and both accumulated and current karmas are destroyed. This service to the Guru is presented as a simple yet profound means to attain liberation and bliss effortlessly.
