What did Baba mean when he told Kakasaheb Dixit that 'Vitthal is a big runaway' and to 'nail him down'?

This profound statement was made immediately after Sai Baba acknowledged Kakasaheb Dixit's vision of Vitthal. As narrated in Chapter 4, Baba told him, "That Vitthal is a big runaway! Nail him down and make him steady. He will escape if you avert your eyes, even for a moment of neglect." This appears to be a metaphorical teaching on the nature of spiritual experiences. Baba was likely advising that divine visions or a state of spiritual connection (represented by Vitthal) are not permanent fixtures. They are fleeting and require constant, unwavering focus, devotion, and vigilance to maintain. A single moment of neglect or a wandering mind can cause the experience to disappear, hence the need to 'nail it down' with firm concentration.
