What is the recommended path for a disciple seeking union with Brahman, according to the teachings in Chapter 16?

According to Chapter 16, the primary path for a disciple to attain union with Brahman (Sayujya) is through faithful service to the Guru. The text emphasizes that all other means will fail and that one must remain humble in this service. It explicitly warns against any neglect or the use of "cleverness" in serving the Guru, as this will lead the seeker into trouble. The core instruction is for the disciple to simply surrender themselves completely to the Sadguru, trusting that the Guru knows the disciple's pitfalls and provides the necessary remedy, even without the disciple's awareness.
