How did Sai Baba's actions and words reinforce the importance of worshipping Vitthal?

Sai Baba consistently reinforced the importance of Vitthal worship through direct instruction, visions, and corrective guidance. Chapter 4 provides several examples of this. He instructed Das Ganu to organize a Name-week (Saptah) and promised a vision of Vitthal if faith was present. He validated Kakasaheb Dixit's meditative vision of Vitthal and encouraged him to "Nail him down and make him steady." Furthermore, He directly intervened in the life of Bhagwantrao Kshirsagar, reminding him of his duty to continue his family's worship of the Vitthal idol, which had been neglected after his father's passing.
