述曰：別解「不議」。絕比無方，故不思議，如《攝論》中以三義解不思議，《顯揚》十七有不思議品，亦不出此三。《瑜伽》等亦然，所以不述。

The Commentary states: Distinctly explaining 'beyond discussion'. It cuts off comparison and is without equal; hence it is inconceivable. Just as in the Mahāyānasaṃgraha it explains 'inconceivable' through three senses, chapter 17 of the Prakaraṇāryavācā has a chapter on the Inconceivable, which also does not go beyond these three. The Yogācārabhūmi and other texts are also like this, which is why they are not cited here.
