The texts describe Sai as both a human form and the embodiment of the infinite. How can I reconcile these two descriptions?

The source material presents Sai Baba as the Saguna form, or a human expression, of the divine. Chapter 10 cautions that those who view him as a mere human are of "dull intellect" because he is far more. He is described as a "mine of Self-knowledge" and the "fullness of Bliss embodied." The reconciliation lies in understanding that his human appearance was an external manifestation, while his internal reality was that of the Supreme Brahman. He embodied the "truly boundless and infinite" principle that is "eternally one and indivisible," which fills all of existence. Therefore, his physical form was a vessel for this ultimate, formless reality.
