According to Sai Baba, what is the relationship between faith in a Guru and the study of scriptures?

Based on the source material in Chapter 19, Sai Baba taught that complete faith in the Guru supersedes the need for cleverness in scriptures or an abundance of other spiritual practices. He is quoted as saying, "No need for abundance of spiritual means, no need for cleverness in the six Shastras; one should have complete faith that the Guru is the doer and the destroyer." This indicates that while scriptures may have their place, the foundational and most critical element for spiritual progress is unwavering faith and trust in the Guru, who is considered the ultimate guide and protector.
