Nichiren the Great Teacher

"As the Buddha indicated in his dying instructions, there will be teachers who propagate the provisional sutras only and never make any attempt to propagate the true sutra. This is perhaps because from past times they have had very close connections with the provisional sutras and have never looked into the true sutra, or perhaps because they have been led astray by the devil and have thus become able to display supernatural powers. But whether they are correct or incorrect in their views is to be judged solely on the basis of the doctrines they expound. It is not to be decided on the basis of whether or not they have keen capacity or can display supernatural powers."
