Sai Baba used an analogy of two fruits to describe spiritual paths. Can you explain what these are and what they represent?

Sai Baba taught about the paths of Knowledge (Jnana) and Devotion (Bhakti) using a powerful fruit analogy. As detailed in Chapter 19, he compared the path of Devotion to eating a Sitaphal, or Custard apple, describing it as an easy, juicy, and sweet means to spiritual attainment that requires little labor. In contrast, the path of Knowledge is likened to a Ramphal, or Bullock's heart fruit. This path is also sweet, but only if one has the immense patience to let it ripen on the tree. If it is plucked too soon or falls, it becomes pungent, symbolizing the difficulty and precision required for the path of Knowledge.
