What are the essential characteristics of a saint like Sai Baba, as described in the text?

According to the descriptions provided in Chapter 11, the essential characteristics of a saint are numerous and profound. They are defined by extreme forgiveness, extraordinary natural calmness, uprightness, gentleness, endurance, and incomparable contentment. Though they appear to have a body and move through worldly life, they are described as being formless, changeless, unattached, and internally liberated. The text further elaborates that a saint is one who is constantly immersed in the Self, always satisfied with whatever comes spontaneously, and who exists beyond the dualities of pleasure and pain.
