Based on Chapter 16, what is the prescribed conduct for a disciple seeking union with Brahman, and what are the potential pitfalls?

According to the teachings in Chapter 16, a disciple should simply surrender themselves completely to the Sadguru, as the disciple is often unaware of their own pitfalls. Serving the Guru with faith is presented as the path to 'Sayujya' (union with Brahman), while other means may fail. The text explicitly warns against even slight neglect in service or the use of 'cleverness' (Chaturai), as these actions can lead a seeker into trouble. Therefore, maintaining firm faith at the Guru's feet and remaining humble in his service is paramount.
