How does V.C. Andrews use imagery in Seeds of Yesterday?

Imagery:

“I don’t explain love, Bart. I don’t think anyone can. It grows from day to day from having contact with that other person who understands your needs, and you understand theirs. It starts with a faltering flutter that touches your heart and makes you vulnerable to everything beautiful.”

“I had heard the wind from the mountains calling me last night, telling me it was my time to go, and I woke up, knowing what to do.”

“The sun was hot and bright. A day for fishing, for swimming, for playing tennis and having fun, and they put my Christopher in the ground.”
