Based on Chapter 22, what specific methods of meditation and devotion does Sai Baba recommend to his followers?

In Chapter 22, Sai Baba offers a simple yet profound path for spiritual practice. The primary instruction is to first cultivate humility, as He says, "Becoming egoless, bow your head to all beings." Following this, a specific meditative technique is given: "Do meditation on a single big toe; It is an easy means of devotion." This practice is directly linked to the story of devotees finding the 'moon' in Baba's toenail. By focusing on this single point on the Guru's form, devotees are given an easy way to still the mind and fulfill their longing for a divine vision, demonstrating a practical and accessible approach to worship.
