How does the author use the analogy of a mother and child to describe the nature of a Sadguru's love?

In Chapter 3, the author, Hemadpant, beautifully illustrates the nature of a Sadguru's love by comparing it to the instinctual affection of a mother for her child. He explains that just as a mother anticipates her child's hunger and provides her breast without being asked, a Sadguru like Sai provides for a devotee's spiritual and worldly needs out of a natural, overflowing compassion. The author notes that the child is unaware of the mother's labor or the value of the ornaments she places on them. Similarly, a devotee may not fully comprehend the depth and workings of the Sadguru's grace, which is described as a rare and fortunate gift.
