In the story of Kakasaheb Dixit, what is meant by the phrase 'the lameness of my mind'?

When Kakasaheb Dixit spoke of the 'lameness of my mind,' he was using a metaphor to describe his spiritual struggles with mental instability. Chapter 51 recounts him explaining to Nana Chandorkar, "I have exhausted myself performing spiritual practices, but the mind does not remain steady." He felt that despite his best efforts at self-control, his mind would inevitably slip away. Therefore, his prayer to Sai Baba was not to fix his physically lame foot, but to 'remove the lameness of my mind.' He was seeking the Guru's grace to achieve mental focus and stability on his path toward attaining ultimate bliss.
