According to the text, how did Sai Baba describe the various forms he takes and what was the ultimate message of this teaching?

In Chapter 9, Sai Baba explains his omnipresence by listing various forms he inhabits. He tells a devotee, "Sometimes I am a dog, sometimes a pig; sometimes I am a cow, sometimes a cat. Sometimes as an ant, a fly, or aquatic creature, in such forms I roam." This was not just a list but a profound teaching. The ultimate message, which Baba explicitly stated, was for the devotee to "renounce the sense of difference; thus alone worship me." He conveyed that true worship and the way to earn his love is to see him in all beings, transcending the apparent distinctions between different forms of life.
