首楞嚴義疏注經 6.441

6.441

以愚癡心，起大我慢，因求尊勝，貪彼供養，此即愛見之惑強而且盛。因起妄語，稱得三乘賢聖果證，實得道果尚不許說，豈況未得而妄說耶。

With a mind of delusion, they give rise to great conceit. Because they seek supremacy and crave their offerings, this delusion of craving and views is strong and rampant. Consequently, they give rise to falsehood, claiming to have attained the fruits and realizations of the worthy ones and sages of the three vehicles. Even if one had truly attained the fruit of the path, one would not be permitted to speak of it; how much less when one has not obtained it and speaks falsely!
