Though they all honor, praise and esteem me, they do not fully understand the meaning and significance of the words they use; not having their own self-realization of Truth they cling to the words of their canonical books, or to what has been told them, or to what they have imagined, and fail to see that the name they are using is only one of the many names of the Tathagata. In their studies they follow the mere words of the text vainly trying to gain the true meaning, instead of having confidence in the one "text" where self-confirming Truth is revealed, that is, having confidence in the self-realization of Noble Wisdom.
