Can you explain the teaching of 'Shraddha' and 'Saburi' using the original Marathi transliteration as found in the text?

The source text presents a crucial teaching on the importance of faith and patience for spiritual attainment. As detailed in Chapter 2, after realizing the folly of debating and the necessity of having a Guru, the author conveys a firm scriptural truth. The text explicitly states, with the Marathi terms transliterated in parentheses, "Without faith (Shraddha) and patience (Saburi), not a bit of the spiritual goal is achieved." This lesson, which Chapter 2 notes was experienced by the author later, is presented as a foundational principle for anyone seeking spiritual knowledge and progress.
