What simple method of devotion did Sai Baba recommend for his followers, and how is it described in the Satcharitra?

Sai Baba offered an easy way for his devotees to practice devotion. As described in Chapter 22 of the Sai Satcharitra, he taught the importance of becoming egoless and bowing your head to all beings. He specifically demonstrated a simple means of devotion by advising meditation on a single big toe. This teaching, which Das Ganu also touches upon in the fourth chapter, is presented as an accessible path for followers to connect with the divine and achieve their spiritual welfare.
