According to Chapter 21, what are the prerequisites for being able to meet a true Saint?

Chapter 21 of the Shri Sai Satcharitra clearly states that encountering Saints and Sages is not a simple matter of being in the right place at the right time. The primary prerequisite is the dawning of good fortune and the presence of God's grace. The author states that without this, even if a Saint is right beside you, a sinful or unfortunate person cannot truly see them. This principle is demonstrated through the author's own story of failing to visit Pir Maulana, which he attributes to his own 'ill-luck' standing in the way of this sacred union.
