2.16

對治者。如病設藥義見序中。我執者有二：一、凡夫情計我，即執五蘊總相，以為主宰。二、外道神我，即蘊離蘊或大或小，幽靈神聖動用難思，皆計為實，故示我執。計一切法實有體性，名為法執。然佛說小乘以除我執。今說般若重為此者，蓋深必該淺也，由是正除法執，兼明我空也。

As for "counteracting": prescribing medicine according to the illness has its meaning shown in the preface. As for grasping at self, there are two kinds: first, the grasping at self through the ordinary person's emotional calculation, which is grasping at the general characteristics of the five aggregates as an agent. Second, the non-Buddhist soul-self: within the aggregates or apart from the aggregates, large or small, an ethereal divine spirit whose operations are hard to conceive, all of which are calculated to be real; hence it is shown as grasping at self. Calculating all dharmas to have real substantial nature is called grasping at dharmas. Now, the Buddha expounded the Lesser Vehicle to eliminate the grasping at self. Here, expounding prajñā does this once more because the deep must include the shallow; therefore it primarily eliminates the grasping at dharmas, while concurrently clarifying the voidness of the person.
