The text mentions 'thorns upon thorns all around' on the spiritual path. How does Baba use these difficulties to strengthen a devotee's faith?

Chapter 29 explains that while the initial spiritual path may seem sweet, it is often followed by significant difficulties, described poetically as 'thorns upon thorns all around.' These challenges can cause doubts to sprout in a devotee's mind. However, the text reveals that Sai Baba himself often creates these obstacles with a specific purpose. The intention behind these trials is to encourage the devotee to remember Sai continuously. By facing these hardships while maintaining remembrance of Him, calamities are overcome. This process is likened to a peg that is shaken and then fixed firmly, purifying and strengthening one's devotion. As verses 128 and 129 state, the power of His name breaks calamities, and the obstacles exist so that remembrance of Sai will occur.
