What is the significance of Shraddha and Saburi according to Hemadpant's experience in the Shri Sai Satcharitra?

According to the experiences shared by the author Hemadpant in Chapter 2 of the Shri Sai Satcharitra, Shraddha (faith) and Saburi (patience) are presented as absolutely essential for spiritual progress. After recounting a personal lesson in humility where Sai Baba curbed his pride in debating, Hemadpant arrives at a profound conclusion. He states firmly, 'Without faith (Shraddha) and patience (Saburi), Not a bit of the spiritual goal is achieved.' This principle is not presented as a detached philosophical concept, but as a firm scriptural truth that he came to understand through direct, personal experience, which he accepted with sincerity.
