The introduction in Chapter 0 focuses exclusively on Sai Baba. It describes his appearance, wearing a kafni, cap, and dhoti. It also highlights his humility; he referred to himself as a 'banda' (servant of God) and often said 'Yaade Haq' ('I remember/meditate on God') rather than making grand claims like 'Anal Haq' ('I am God').
