What was Sai Baba's specific explanation for showing partiality towards the food brought by Mrs. Khaparde?

When Madhavrao pointed out the 'partiality' of Sai Baba eagerly eating Mrs. Khaparde's food while ignoring others, Baba gave a mystical explanation. As recounted in Chapter 27, Baba revealed his connection to her soul through its past incarnations. He stated, "In a previous birth, this was a grocer's cow, very milky and plump." He then traced her subsequent births to a gardener, a Kshatriya, and a grocer's wife, before her current life in a Brahmin family. Baba concluded by saying, "after a long time, I have seen her; let me have two morsels of love in my stomach for happiness and satisfaction." This revealed that his actions were not based on worldly likes but on a deep, timeless spiritual connection and the pure love with which the offering was made.
