Based on the story of Radhabai Deshmukh, what does it mean that Baba sometimes tests a devotee's love and devotion to the limit?

The story of Radhabai Deshmukh serves as a powerful illustration of Baba testing a devotee. As mentioned in Chapter 18, Baba sometimes puts a person's devotion and love to the test before giving instruction. Radhabai's intense desire for a mantra led her to undertake a severe fast, renouncing food and water for three days. This act of "Prayopavesha" (fasting unto death) pushed her to her physical and emotional limits. This trial, which caused great worry to others like Shama, can be seen as the test of her faith and resolve that Baba allowed to unfold before He would fulfill her heart's desire.
