What is the meaning of the 'necklace of nine gems' mentioned in relation to Appasaheb's story?

In Chapter 33, the text describes that for the one whom Baba's hand touched, it is like receiving a 'necklace of nine gems.' This is a powerful metaphor for the spiritual reward of devotion. It does not refer to a literal piece of jewelry but symbolizes the 'treasure of ninefold devotion and love' (Navadha Bhakti) that a devotee receives. This imagery elevates the act of fulfilling a promise to Baba beyond a simple transaction. It becomes a profound exchange where, in return for their offering, the devotee is graced with the invaluable treasure of devotion and a form of Baba's remembrance.
