What philosophical reason is given in Chapter 39 for Sai Baba's incarnation, and who were the intended beneficiaries of his grace?

Chapter 39 presents a profound, philosophical reason for Sai Baba's presence, stating he came 'of his own accord' for the 'upliftment of his devotees.' The text moves beyond a simple historical account to explain a divine mission. It specifically identifies the intended beneficiaries of his grace, posing the question of who else but Sai would uplift 'the dull-witted, the fallen, and the poor, those without vows, penance, or sacraments—simple and faithful people.' This passage from Chapter 39 highlights that his purpose was to offer salvation to all, especially the humble and devout.
