OM

"Fear struck deep into Siddhartha  SO this was the way things stood with him! He was so lost, so confused and forsaken by all wisdom that he had had as a child to d=find peace, had grown so large he had sought it in the dissolution of his body." (Hesse 93).

Siddhartha thought he had experienced all that life had to offer, that he obtained all the wisdom there is, he had experienced all the happy things and love, as well as all the pain and suffering; and there isn't anything else for him for that he feel depressed and tries to drown himself in the river. But as he starts to drown, fear strikes him and he remembers OM, the very holy words that drove and inspired him to begin his journey away from home. He sits by the river bank, repeating OM, and he has awakened , once again.
