Absolutely:
"The path to Buddhahood is not to be found in the Flower Garland doctrine of the phenomenal world as created by the mind alone, in the eight negations of the Three Treatises school, in the Consciousness-Only doctrine of the Dharma Characteristics school, or in the True Word type of meditation on the five elements of the universe. Only the T’ien-t’ai doctrine of three thousand realms in a single moment of life is the path to Buddhahood."
and
"The essence of the sutras preached before the Lotus Sutra is that all phenomena arise from the mind. To illustrate, they say that the mind is like the great earth, while the grasses and trees are like all phenomena. But it is not so with the Lotus Sutra. It teaches that the mind itself is the great earth, and that the great earth itself is the grasses and trees. The meaning of the earlier sutras is that clarity of mind is like the moon, and that purity of mind is like a flower. But it is not so with the Lotus Sutra. It is the teaching that the moon itself is mind, and the flower itself is mind. You should realize from this that polished rice is not polished rice; it is life itself."
