Symbolism, Imagery, Allegory
Okay, we know Dr. Fried is a doctor and not a gardener. But the way she talks about seeds all the time? Well, we're betting her garden at home is blossoming all year round.
When Dr. Fried discusses the possibility of Deborah getting better, she refers to the hidden strength in Deborah as "the buried seed of will and strength" (3.54). Dr. Fried refers to this seed of hidden strength repeatedly during their three years of intensive therapy together.
What's she really trying to say here?
A seed holds within it the possibility of life. It's literally a little pod full of potential, but it will only grow if nurtured and given the right conditions in which to grow. Deborah has the potential in her to be healthy, just as a seed has the potential to grow into a beautiful, full-grown, healthy, sturdy plant.
Luckily, Dr. Fried has the green thumb to help.
