What metaphors does Chapter 18 use to illustrate the nature of the Guru and the experience of approaching them?

Chapter 18 employs several vivid metaphors to explain the Guru's nature and the devotee's experience. To describe the transformative process of approaching the Guru, it uses the analogy of a salt doll entering the ocean, which dissolves and becomes one with it, signifying the merging of the individual self into the divine. To illustrate the Guru's role as a bestower of universal wisdom and blessings, Chapter 18 compares the Guru to "the rain clouds of the monsoon, showering the water of self-bliss with love." These metaphors powerfully convey the concepts of surrender, non-duality, and the Guru's boundless grace as detailed in the chapter.
