How does Baba explain the importance of serving others, and what is considered the ultimate form of service?

Baba explains the profound importance of service by revealing his omnipresence. According to chapter 3, he states, "This entire visible world is my form—the insect, the ant, the poor, the king." This implies that serving any being is equivalent to serving him. However, the text also highlights a hierarchy of service. The narrator contemplates abandoning the "service of men" to be in the "service of the Guru." This shift is justified later in chapter 3, which clarifies that among all places of worship, "the Guru is supreme." Therefore, while serving the world is a way to serve God's form, direct service and devotion to the Guru is presented as the highest path.
