Shingon Buddhism is a major school of Japanese Buddhism that emphasizes esoteric teachings and practices. Founded in the early 9th century by Kūkai, also known as Kōbō Daishi, it focuses on rituals, meditation, and the use of mantras and mandalas to achieve enlightenment. The term "Shingon" means "true word," reflecting the importance of sound and language in its practices. Followers believe that through these sacred teachings, one can connect with the cosmic truth and attain spiritual awakening. Shingon Buddhism is known for its rich symbolism and elaborate ceremonies, often incorporating elements of Taoism and Shinto.
