"This wisdom unhindered after preparation..." and so forth: the preceding moment is the path of preparation, and the subsequent moment is the penetration. The preceding preparation ceases, and the penetrating wisdom arises; hence it is called "preparation." "Unhindered" means that the preceding must cease before the subsequent thought can arise, offering no obstruction to the subsequent thought; hence the cessation of the preceding thought is called unhindered. Alternatively, when the preceding thought ceases, the subsequent thought immediately arises without another thought intervening; this is called unhindered. Although there are two explanations, the former interpretation is superior.
