A simile is a figurative language employed when we compare one thing to another while using the words "like", "as" or "such as." The line, for example, uses simile when comparing how "the heights of my love" flew to how a dove flies while using the word "as": "as a dove."
This type of figurative language is often used to make the writing more colorful, meaningful and interesting.
