I searched for a specific saint, but the text doesn't mention them. What is Sai Baba's teaching on saints who are not named in the Shri Sai Satcharita?

While the name you seek may not be specifically mentioned, the teachings in Chapter 19 offer profound guidance. The text suggests that the sense of difference, such as focusing on one specific name versus another, can be like a 'wall' that hinders reaching a state of non-duality. The core message is to focus on the one Master, referred to as 'Allah-Malik,' who is the sole protector. The practice of devotion itself is the secret, for as Chapter 19 states, 'As the action, so the hearing; as the practice, so the benefit.' Therefore, the spirit of your devotion is more important than the specific name used.
