A Failure Stands Tall!

is episode 47 episode of the original Naruto anime.

Synopsis
Pulling back Hinata's sleeve, Neji reveals that he had hit several points on her arm called tenketsu, special glands that produce and maintain the flow of chakra, during their close combat. With all of them tapped, Hinata's chakra flow to her hand is effectively cut off and her blow to Neji's heart has no effect. Neji continues his assault, but Hinata continues to stand up, inspired by Naruto. She tells Neji that she believes that he is suffering more from fighting his destiny. Angered, Neji attempts a fatal blow, but four observing Jonin halt him. Hinata collapses into cardiac arrest shortly after, and Naruto vows to avenge her.
