Based on the provided text, can you describe Sai Baba's unique teaching methodology?

Sai Baba's teaching style is portrayed as being natural, spontaneous, and all-pervasive. According to Chapter 19, Sai does not require a specific time or a formal place for imparting wisdom; his teaching happens organically while sitting, standing, or walking. The core of his method is indirect guidance, where he uses circumstances and other people to deliver his message, reflecting his compassion and omnipresence. A clear example is when he inspires a devotee to sing a song about Rama at the exact moment another devotee needed encouragement for that specific practice. This shows how Baba could reflect the state of a person's inner heart and provide direct proof and instruction without uttering a single word himself.
