Chapter 26 mentions the world being like a dream. Can you elaborate on this analogy and how one 'wakes up'?

In Chapter 26 of the Sai Satcharitra, the world is compared to a dream to illustrate its illusory nature. The text explains that just as a dream born of desires feels real but disappears upon waking, the world perceived by the senses dissolves when one attains a true state of wakefulness. According to the chapter, this 'waking up' is achieved through the 'Great Sayings' or Mahavakyas imparted by a Sadguru. When the time is right for this awakening through the Guru's word, the illusion ceases and the light of non-dual bliss shines forth.
