The spiritual path is described as having "thorns upon thorns." How does this experience relate to the development of faith and the emergence of doubt?

The description of the spiritual path having "thorns upon thorns," as mentioned in Chapter 29, points to the inevitable difficulties that arise after an initially sweet beginning. This challenging phase is directly linked to the development of faith because it is designed to test the devotee. The text acknowledges that these hardships naturally cause doubts to sprout in the mind, leading one to question, "Why does Sai bring these obstacles?" However, Chapter 29 advises that this very moment of doubt is the critical point where one must "hold on firmly to faith." These trials are not meaningless; they are the tests through which firm, unshakable faith is forged and enters the devotee's heart.
