What are the spiritual benefits promised to devotees who sing or listen to Sai Baba's life story?

Chapter 3 details numerous spiritual benefits for devotees. Sai Baba promises that for anyone who sings his life story and deeds with fondness, "I will stand before, behind, and on all four sides of him." Listening with devotion is said to make the consciousness of worldly affairs fade away, allowing waves of devotion and love to rise, which yield "gems of knowledge." For those who perform his kirtan (devotional singing), Baba promises to give the "cloud of joy" and eternal happiness and peace. Ultimately, he gives his vow of liberation to anyone who surrenders solely to him, worships him with faith, and constantly remembers him.
