How does Chapter 52 explain the philosophical journey from worshipping the form (Saguna) to realizing the formless (Nirguna) Absolute?

Chapter 52 delves into the advanced spiritual concept of realizing the formless Self through devotion to the Guru's physical form. It teaches that by meditating immensely on Sai's physical, or Saguna, form, the subtle nature of the Self will eventually manifest as the attachment to the form itself vanishes. The chapter notes that the attributeless Parabrahma is entirely difficult to understand directly, so entering the Saguna form is a necessary step. It uses the metaphor of two lamps embracing to become one light, explaining how duality vanishes when a devotee takes refuge in the Guru, leading them mysteriously toward the supreme goal of liberation.
