Following the narrator's account of the story, what specific guidance did Sai Baba provide on the practice of meditation for spiritual realization?

As detailed in Chapter 19, after hearing how the story affected the narrator, Sai Baba gave a discourse on attaining true knowledge of the Soul. He stated that meditation (Dhyana) is necessary for this. He advised becoming free from all desires and meditating on the one who resides in all beings. Baba offered two paths: meditating on his formless nature, which he described as pure knowledge or a cloud of bliss; or, if that is not possible, meditating on his physical form (Saguna) from head to toe. This practice, he explained, leads to a one-pointed mind and ultimately results in oneness with Brahman.
