Why is a human birth considered so valuable and rare in the context of Sai Baba's teachings?

Chapter 14 of the Shri Sai Satcharitra emphasizes the immense value of human life by stating that a soul attains a human body only 'by the strength of infinite merit.' This implies that our existence as humans is not a common occurrence but a significant achievement resulting from countless past good deeds. The text further clarifies that among those who receive this rare gift, the 'exceptionally fortunate ones' are those who understand spirituality. This positions human life as a precious and unique opportunity to pursue a higher, meaningful existence beyond mere worldly involvement.
