How does Chapter 15 contrast the concepts of internal attachment versus external religious display in the path of devotion?

Chapter 15 masterfully contrasts internal attachment with external display through two key examples. It champions heartfelt attachment using the profound analogy of kittens whose 'total devotion' and persistent clinging to their mother cause her love and milk to flow, symbolizing how unwavering inner love melts Sai's heart. This illustrates that true connection is an internal, loving persistence. In stark contrast, the chapter recounts how Sai Baba questioned Das Ganu's elaborate attire for a kirtan, asking why he needed a turban and tunic, and stating, 'We do not need all that.' This critique of external formality underscores the teaching that genuine devotion is not found in outward show but in the sincere, loving attachment of the heart.
