What does a devotee need to do to attain welfare and cross the "seven seas," according to Sai Baba's teachings?

According to the teachings shared in Chapter 13, the path to attaining welfare is rooted in simple, unwavering faith and devotion rather than complex rituals. Sai Baba makes a profound promise to his devotees, stating, "If you constantly say 'Sai Sai,' I will take you across the seven seas." He assures them that if they keep faith in these words, they will certainly achieve their welfare. This is because Baba doesn't require elaborate offerings; instead, he emphasizes that he resides where there is boundless devotion (bhava). He also notes that only the righteous, whose sins have vanished, have truly taken to his worship.
