According to Sai Baba, what is the single most important requirement for a disciple, and what is not needed?

Based on his own experience, Sai Baba taught that the most important requirement for a disciple is unwavering faith and undivided attention towards the Guru. As he explains in Chapter 19, one does not need an 'abundance of spiritual means' or 'cleverness in the six Shastras.' Instead, a disciple should have 'complete faith that the Guru is the doer and the destroyer.' Baba's Guru desired nothing more than his disciple's constant contemplation. Baba passed this teaching on, saying, 'Look at me with undivided attention, and I will look at you the same way; my Guru did not teach me anything else.' This shows that the core of the path is a relationship of focused faith, not intellectual or ritualistic complexity.
