Beyond faith and patience, what does Chapter 2 identify as the most fundamental prerequisite for attaining any spiritual knowledge or achieving a spiritual goal?

Chapter 2 asserts that the most fundamental prerequisite for any spiritual attainment is having a Guru. The text makes this point unequivocally, stating, "Without a Guru, there is no knowledge or spiritual goal; this scriptural truth is firm." To reinforce this, the author provides powerful examples, noting that even divine incarnations like Rama, who "held the feet of Vasistha," and Krishna, who "bore the hardship of gathering wood at Sandipani’s house," submitted themselves to a Guru. Only after establishing this primary necessity does the chapter mention that "Without faith (Shraddha) and patience (Saburi), Not a bit of the spiritual goal is achieved," positioning these virtues as essential but dependent on the foundational relationship with a Guru.
