What was Sai Baba's reaction when people were unkind to each other, and what does this reveal about his teachings?

Sai Baba felt a profound and personal connection to the suffering of others. In Chapter 44, he explicitly states, "If someone spoke sarcastically to another, He has touched my very vital point; know that it has pierced my heart." He further clarifies that even harsh words directed at someone else immediately caused him pain. Conversely, he was greatly pleased by those who endured mistreatment with patience. This reveals a core teaching: Sai is "filled inside and outside of all beings," and therefore, harming another person is equivalent to harming Sai himself. His only liking is for love.
