Letter to the Brothers
(Monthly Gosho Passage November 2009)
If you propagate it, devils will arise without fail. Were it not for these, there would be no way of knowing that this is the true teaching. One passage from the same volume reads, "As practice progresses and understanding grows, the three obstacles and four devils emerge, vying with one another to interfere...You should be neither influenced nor frightened by them. If you fall under their influence, you will be led into the paths of evil. If you are frightened by them, you will be prevented from practicing true Buddhism." This quotation not only applies to Nichiren but also is the guide for his disciples. Reverently make this teaching your own and transmit it as an axiom of faith for future generations.
