What is the importance of mysticism in the story, Hapworth 16, 1924?

The seven-year-old Seymour in his letter reveals the strong influence on his beliefs of Indian religious mysticism, particularly the Vedanta branch of Hinduism. In this connection a functioning belief system becomes evident as the infant terrible matter-of-factly prophesies future events in his life and the lives of certain other Glass family members, especially Buddy. Foreknowledge and predestination, reincarnation (e.g., Seymour's allusions to his "appearances"), and revelation help shape the oracular, egocentric world view by which he lives.
