What does Chapter 16 say a disciple must do to attain union with Brahman, and what should they avoid?

Chapter 16 of the Sai Satcharitra clearly outlines the path for a disciple seeking ultimate realization. The primary duty is to serve the Guru with unwavering faith and humility, as this service is the means to attain union with Brahman (Sayujya). A disciple should simply surrender themselves completely to the Sadguru, trusting that the Guru knows their pitfalls and will provide the necessary remedy. The chapter explicitly warns against any neglect in service or the use of one's own 'cleverness' (Chaturai), as this will only lead the seeker into trouble. Therefore, maintaining firm faith at the Guru's feet is absolutely essential.
