Can you explain the specific challenges Balasaheb Deo faced in his spiritual practice, as described in the Shri Sai Satcharita?

The Shri Sai Satcharita details the struggles of Balasaheb Deo, a devotee who deeply desired to read the sacred text Dnyaneshwari daily. As recounted in Chapter 41, Deo found that despite his strong intention, various obstacles would constantly prevent him from maintaining this practice. Even when he took a three-month leave from work, he managed to read other books but could not fulfill his wish to read the Dnyaneshwari. The text mentions that whenever he tried, doubts would surface in his heart, preventing him from developing a true love for the reading and keeping it superficial. This difficulty persisted to the point where he couldn't even manage to read five verses a day with regularity.
