Can you provide a summary of the key events and teachings presented in Chapter 22 of the Shri Sai Satcharitra?

Chapter 22 begins with invocations to the Sadguru, praising him as the remover of worldly fears and the embodiment of bliss. The chapter then uses a powerful metaphor, as described in its verses, comparing the nature of illusion and reality to mistaking a rope for a snake in dim light, stating that the Guru both creates and dispels this illusion. It expresses the deep yearning of devotees to meditate on Baba's form, considering his feet the sole path to happiness. A key event detailed in Chapter 22 is when Das Ganu wishes to visit Prayag for a holy bath. Baba instructs him that his own big toe is Prayag, and upon Das Ganu placing his head at Baba's feet, the holy waters of the Ganga and Yamuna miraculously manifest from the toe.
