Why is Tang Sanzang said to be a coward?

It would be unfair to say that Tang Sanzang was a coward. It should be said that it was due to the "cowardly nature" of Buddhist culture. The reason why Tang Sanzang became a eminent Buddhist monk was that he must be able to profoundly interpret and strictly follow the "cowardly" Buddhist tenets of forbearance and ahimsa. Therefore, being a coward is not determined by his character, but by his professional ethics.
