Neither influenced nor frightened by the three obstacles and four devils

[T'ien-t'ai writes:] "As practice progresses and understanding grows, the three obstacles and four devils emerge in confusing form, vying with one another to interfere. . . . One should be neither influenced nor frightened by them. If one falls under their influence, one will be led into the paths of evil. If one is frightened by them, one will be prevented from practicing the correct teaching." This statement not only applies to me, but also is a guide for my followers. Reverently make this teaching your own, and transmit it as an axiom of faith for future generations. 16/4
