The concept of Om signifies the unity and perfection of the universe. Siddhartha’s periodic recognitions of Om punctuate moments of awakening in his life and function to further guide his reflection and spiritual growth. He first meditates on Om as a boy in his hometown, helping him decide to leave town for further spiritual growth. Later in the book, on the brink of his suicide, Siddhartha recalls Om and it sooths him, reminding him of his true objective. Ultimately, when Siddhartha attains enlightenment, it is through a profound recognition of Om through meditation on the river.
