Sai Baba gave some very specific warnings about the kind of people to avoid. Can you explain who he was referring to and how strongly he felt about it?

In Chapter 3, Sai Baba gives stern advice about social conduct. He urges that one should abandon those who have abandoned religious conduct, calling them very dangerous. His warning was severe: he advised to move aside when they come near and not even to stay in their shadow, even if it means enduring suffering. He describes such individuals as those whose character is fallen, who are thoughtless, whose actions are ruined, and who cannot distinguish between what is desirable and undesirable. Baba questioned how such a person could ever achieve their goals, emphasizing the importance of associating with people of good character.
