The text mentions a 'necklace of nine gems' and 'ninefold devotion'. What is the significance of this in the context of Sai Baba?

In Chapter 33, the text uses rich symbolism to describe the connection with Sai Baba. It states that for a person whom Baba's hand touched, the experience was like receiving a "necklace of nine gems." This is further explained as receiving a treasure of "ninefold devotion and love" and serving as a form of remembrance of Baba. The text also alludes to a "nine-donation" that would be understood in the context of Baba's Mahasamadhi. While not explicitly defined, the symbolism points towards the concept of Nava-vidha Bhakti, or the nine forms of devotion in Hindu tradition. Therefore, this imagery signifies the profound and complete spiritual treasure of love and devotion gifted by Sai Baba to his followers.
