What underlying spiritual principle does Chapter 29 suggest is at play regarding who receives blessings from Sai Baba?

Chapter 29 suggests that receiving a blessing from Sai Baba, such as money, was not arbitrary but governed by a spiritual principle related to destiny and timing. The text explicitly states that although Baba was merciful, he did not give to all who came to him. It explains this by saying, "Whoever's auspicious time had arrived - only for them this blessing of happiness." The physical act of receiving something from a saint's hand was considered a form of great fortune, a "shell of fortune" obtained only by the truly fortunate. Therefore, his seemingly unpredictable giving was a manifestation of bestowing grace upon those who were destined to receive it at that specific moment.
