"But there were times when Miss Keough all but confided that the requirements of knowing the code of Literature were tedious; and there were other times when—even among these things we were supposed to read—she would present some poem or story as if it belonged, not to a reading list but to her own life...This poem "Heat" by H.D. we understood was offered so. It belonged not to the order of poems and stories that we must know all about if we were to be accomplished students. It belonged to the second order that seemed to contain a personal revelation. It was the ground for a possible deeper communion."
Robert Duncan, The H.D. Book.
