The Zen sect asserts that enlightenment is not to be found in the pursuit of doctrinal studies, but only through the direct perception of one’s own mind with the practice of meditation. Nichiren Shoshu Buddhism is based on the Lotus Sutra, which is the Buddha’s legitimate teaching. Nichiren Daishonin stated:
Thus, their arguments are based merely upon the worlds of the teachers of doctrine and not upon the Buddha’s teaching. The Daishonin said:
Therefore, we can attain enlightenment only through the teachings of the Lotus Sutra, but we cannot manifest the Buddha nature by the practice of mere meditation.
