The introduction in Chapter 48 mentions that the previous chapter discussed rebirth and karma. Based on that previous chapter's teachings, what is the step-by-step process for a devotee to completely avoid rebirth?

While Chapter 48 acknowledges that the previous chapter narrated that one takes rebirth to settle debts and experience karma, the provided text does not contain the specific step-by-step process from that chapter. Instead, Chapter 48 offers its own guidance for spiritual liberation. It states that by listening to the Sai Satcharitra with an alert mind, 'crossing the ocean of existence becomes easy as the bonds of Karma are broken.' Furthermore, it suggests that serving Sai’s feet with a devotional spirit and remembering him ensures that 'crossing the ocean of existence becomes easy and certain.'
