Can someone recommend a book in a way that will reliably produce a therapeutic result? So much of the positive effect of reading is dependent on the right book at the right time.
The book you read is not necessarily the same book I read. I.e., what works for me may not do the same for you. Which is one of the mysteries of the reading process, placing bibliotherapy within the realm of mystical consciousness more than practical application.
Reading becomes background noise for a walk through our memories. We are semiconscious of both and responsive to the amalgamation. Do we cry for the tragedy of the book's characters? No, it is our own tragedy that overwhelms us.
And yet, it is the artistic representation that is often able to speak to and call forth the emotion in a manner of which we are incapable left to our own devices. However, from the evocation we might find a way to utilize our own experience in a way that is also creative, culminating in a domino effect, aka inspiration.
