How does Melvin Konner use imagery in Becoming a Doctor: A Journey of Initiation in Medical School?

Imagery:

"This book is a compensatory pause. The 'abnormal beat' was a medical education that took place at the wrong time - in my mid-thirties, after I had settled in to another, promising career and also into a marriage and a family. It was as if the electrical stability of my life, the normal rhythm of the soul, was temporarily disrupted; there was a need to gather one's forces for the next normal beat." Pg 5
