50.8.p21

“It’s like someone who leaves a village in search of a dangerous snake. If they see an enormous snake, they grab its tail with their left hand, but that snake’s head twists around to bite them. As a result of that, their life may well end. This person is likewise. Suppose a foolish person studies the teachings in the twelvefold sūtras and doesn’t do it adequately for any one of them or examine their meaning. The reason is that they make use what’s not the ultimate meaning of the correct teaching.
