What divine attributes of the Guru are mentioned in Chapter 16, and what reason is given for him taking a physical form?

The opening verses of Chapter 16 praise the Guru with lofty attributes, calling him the "Stainless (Niranjana), the Imperishable (Avyaya), the One beyond attributes (Gunatita), the King of Yogis." He is described as an ocean of Truth, Consciousness, and Bliss. Despite this transcendent, formless nature, the chapter gives a clear reason for his incarnation in a physical body. As the text states, "You have taken this body for the sake of helping others, to uplift the poor and lowly." This highlights the Guru's immense compassion and his primary mission to guide and elevate humanity.
