What does Chapter 52 say about the importance of meditating on Sai's physical form (Saguna)?

According to the teachings in Chapter 52, meditating on Sai's physical or Saguna form is a crucial step in spiritual realization. The chapter explains that without first entering the Saguna form, the light of the true Self cannot be known. It posits that the ultimate reality, the formless and attributeless Parabrahma, is "entirely difficult to understand" on its own. Therefore, by meditating immensely on Sai's physical form, the devotee allows the subtle nature of the Self to manifest as the attachment to the form eventually vanishes. This process shows how Sai used his form to lead devotees toward the supreme goal.
