仁王般若經疏 2.84

2.84

From "therefore prajñā" onward is the fourth major section, explaining that prajñā forgets words and is free from attachment. Within this there are two [parts]: first, giving rise to practice based on emptiness; second, praising the teaching. Within giving rise to practice, there are four clauses: first, explaining that it cannot be apprehended as practicing within sentient beings and yet practicing, because the emptiness of sentient beings is nonexistent; second, that it cannot be apprehended as practicing within the pañca-skandha and yet practicing, because the emptiness of phenomena is nonexistent; third, that it cannot be apprehended as practicing within the objective sphere and yet practicing, because the emptiness of the objective sphere is nonexistent; fourth, that it cannot be apprehended as practicing within understanding and yet practicing, because the emptiness of knowing is nonexistent. In the second part, praising the teaching, there are three [aspects]: first, "therefore prajñā is inconceivable," praising the fourteen prajñās; second, that giving birth to all buddhas of the three times is inconceivable; third, knowing that the conventional is illusory and yet being able to transform and benefit.
