Could you list the essential qualities of the Sadguru as portrayed in Chapter 16?

Chapter 16 of the Sai Satcharitra describes the Sadguru with several profound attributes. He is hailed as 'Niranjana' (the Stainless), 'Avyaya' (the Imperishable), and 'Gunatita' (the One beyond attributes), signifying his transcendent nature. He is also called the 'King of Yogis.' The text states He is an 'ocean of Truth, Consciousness, and Bliss.' A key quality mentioned is that He is 'Aptakama,' meaning his desires are always fulfilled, making him inherently desireless. Furthermore, his speech is compared to the 'river of nectar from the ocean of Vedanta,' and he wields the 'sword of Knowledge,' which causes the tree of worldly existence to tremble, highlighting his role as a source of ultimate wisdom as per the descriptions in Chapter 16.
