How did Sai Baba's personal experience with his own Guru demonstrate the principles of faith and patience?

Sai Baba's recounting of his time with his Guru in Chapter 19 serves as a powerful testament to faith and patience. He mentions staying at his Guru's feet for twelve years, an act of immense patience and endurance. His faith is evident in his complete devotion and absorption in his master. He states, 'I would gaze at my Guru's face with love day and night; I felt neither hunger nor thirst; without the Guru, my mind was restless.' This constant contemplation was the only thing his Guru expected. In return for this unwavering faith and patience, Baba received immense love, protection from trouble, and spiritual nourishment, highlighting the profound rewards of embodying these two virtues in the Guru-disciple relationship.
