"The greatest caution is needed in these matters!" -- Nichiren

"Ordinary people in the world can easily understand why those who commit crimes motivated by stinginess or greed or who rob and steal should fall into the world of hungry spirits. But it takes someone of wisdom to understand that, though one may be a good person, free of stinginess, greed, or such faults, if he slanders the Law, or merely associates closely with those who slander the Law and thoughtlessly believes their doctrines, he will fall into the world of hungry spirits. The greatest caution is needed in these matters!" -- Nichiren

For example: Those who thoughtlessly believe in Soka Gakkai's warped mentor-disciple and interfaith doctrines.
