妙法蓮華經玄贊 3.95

3.95

贊曰：上半頌頌前所得難解菩提涅槃智慧甚深，後半頌頌前所說難知智門甚深，以二乘不知故皆無能問者。

The Commentary says: The first half-verse versifies that what was attained before is difficult to understand—the profound wisdom of bodhi and nirvāṇa. The second half-verse versifies that what was proclaimed before is difficult to comprehend—the profundity of the wisdom-gate. Because the two vehicles do not know it, none were able to question it.
