Could you outline the core principles of Sai Baba's teachings on kindness and unity as described in the provided excerpts?

Based on the excerpts from Chapter 10, Sai Baba's core principles centered on unity and active kindness. He taught that one must not retaliate against harm but should instead offer a favor. He actively worked to dissolve religious conflict by teaching that God is one, whether called Ram or Rahim, and urged people to unite. He also advised against argumentation and competition, encouraging followers to focus on their own welfare, which Shri Hari would protect. This compassionate path, free from the pride and greed of false gurus, was presented as a straightforward way for all to attain spiritual well-being.
