2.142

Śāriputra said: "Why do you not transform your female body?" (Below, the fourth part clarifies the distinction between transforming and not transforming with respect to marks. The Hinayāna grasps at marks and definitely has something to transform; the Mahāyāna's marks are fundamentally markless, and therefore there is nothing to transform. This is the first, the question. [Seng]zhao says: "Having unobstructed wisdom yet an obstructed body, why do you not transform and abandon it?")
