How does Chapter 22 synthesize the concepts of form and formlessness in relation to the Sadguru, and how is this illustrated through devotee experiences?

Chapter 22 masterfully synthesizes the concepts of the Sadguru being both formless and with form. It begins by describing the Guru as the formless one, existing even before the illusion of 'snake and rope' came into being. However, it also acknowledges the Guru as the one who takes a form to guide devotees. The chapter beautifully illustrates this by describing how devotees long for the sight of Baba's form. This desire for the form is fulfilled through a tangible experience at His feet. The text explains the 'logic of the branch and the moon,' where the nail on Baba's big toe becomes the crescent moon, a visible object of meditation that fulfills the devotees' longing. This shows how the formless principle manifests in a perceivable form to grant bliss, as further exemplified by the Ganga and Yamuna manifesting from His toe for Das Ganu.
