What did Kakasaheb Dixit mean when he spoke of his 'lame' mind to Nana Chandorkar?

When Kakasaheb Dixit referred to his 'lame' mind, he was using a metaphor to describe his spiritual struggles. As detailed in Chapter 51, he told Nana Chandorkar that he was not worried about his physical lameness, as the entire body is perishable. His real concern was his mind, which he found was not steady. He explained that despite his best efforts at spiritual practices and self-control, his mind would slip away, and he felt exhausted by this lack of focus. Therefore, he decided to visit Sai Baba not for his foot, but to pray for the healing of this 'lameness of my mind'.
