Can you explain what 'Shraddha' is and why it's so important based on Chapter 2?

In the context of the Shri Sai Satcharitra, 'Shraddha' is explicitly identified as faith. As Chapter 2 reveals, it is one of the two most crucial qualities for anyone on a spiritual journey, the other being patience (Saburi). Its importance is stated in absolute terms: "Without faith (Shraddha) and patience (Saburi), Not a bit of the spiritual goal is achieved." This is presented as an unshakeable scriptural truth. The narrative connects this need for faith to the importance of humility and the necessity of a Guru, suggesting that Shraddha is the foundational belief and trust that enables a devotee to overcome pride and receive the knowledge needed for spiritual attainment.
