Final answer:
Orual denies feeling elation at the beauty of nature due to a sense of existential insignificance and her personal turmoil which prevents her from connecting with the natural world.
Step-by-step explanation:
Orual denies the feeling of elation rising in her at the beauty of nature for two primary reasons. First, she may feel that nature is indifferent to her existence, which can lead to a sense of insignificance and a consequent resentment towards the natural world. This can evoke a feeling of wanting to lash out or feel hatred for not being able to alter or affect nature. Second, she could feel that her own personal circumstances and inner turmoil make it impossible to truly connect with the beauty of nature. Her struggles may make her feel unworthy or incapable of experiencing such elation, as the natural world is a stark contrast to her own pain and discontent. These reasons show a complexity in Orual's character and an inner conflict between a desire for beauty and her ability to experience it.
