What does Chapter 52 say about the importance of Sai's physical form, the Saguna, in the path to spiritual realization?

In Chapter 52, the importance of meditating on Sai's physical form (Saguna) is highlighted as a crucial step towards spiritual understanding. The text explains that the subtle nature of the Self will only manifest as the attachment to the Saguna form vanishes. However, it clarifies that one cannot bypass this step, stating that without first entering the Saguna form, the light of the Self cannot be known. This is because the ultimate reality, the Parabrahma, which is without attributes, is considered entirely difficult to grasp directly. Therefore, meditating on Sai's form is the prescribed method to mysteriously lead faithful devotees toward the supreme goal.
