Can you explain the metaphor of the 'rag' and the 'shawl' in the context of Baba's teachings on spiritual study as given to Deo in Chapter 41?

In the narrative from Chapter 41, the 'rag' symbolizes the fragmented, second-hand spiritual knowledge Deo sought by inappropriately questioning others like Balkram about their personal methods of worship and meditation. Sai Baba was displeased with this, considering it an act of 'stealing' when He Himself was available for direct guidance. In contrast, the 'beautiful golden-bordered shawl [Shela]' that Baba mentioned He was ready to give represents the complete, profound, and authoritative spiritual wisdom that only a Guru can bestow. The incident concludes with Baba ordering Deo to read the scriptures regularly, which Deo accepts as the true 'shawl'—the sanctioned path to knowledge, replacing his misguided attempt to collect 'rags'.
