How are the concepts of Shraddha and Saburi related to the role of a Guru as described in the provided text?

Chapter 2 intricately links the concepts of Shraddha (faith) and Saburi (patience) to the necessity of a Guru. The text posits the firm scriptural truth that "Without a Guru, there is no knowledge or spiritual goal." It immediately follows this by stating that without Shraddha and Saburi, no spiritual goal can be achieved. This implies that faith and patience are the prerequisite attitudes a disciple must have to approach a Guru and receive knowledge. The chapter reinforces this by citing how even divine figures like Rama and Krishna humbly served their Gurus, Vasistha and Sandipani, demonstrating that true wisdom requires surrendering pride.
