Besides providing spiritual bliss, what is the ultimate purifying purpose of narrating the 'Sai Charitra' as suggested at the end of the introductory section of Chapter 36?

Beyond delivering the "water of self-bliss" and removing worldly misery, Chapter 36 suggests a broader, universal purpose for narrating the Sai Charitra. The text mentions that Sai Baba has "redeemed infinite beings" and that his devotion has spread both within the country and abroad. The narration of his life story is presented as a continuation of this redemptive work. The chapter concludes with the invocation, "May the ears of the listeners and the mouths of the speakers everywhere be purified." This implies that the ultimate purpose is a collective purification and spiritual upliftment for all who engage with the holy life story of Sai.
