問：既言「雙印」，印二取空及依他有即是觀俗，印二空性謂真勝義即是觀真。真、俗雙觀五地方得，云何地前已能合觀？

Question: Since it says "confirming both," confirming the emptiness of the two graspers and the existence of the other-dependent nature is the contemplation of the conventional, while confirming the nature of the two emptinesses as the true ultimate reality is the contemplation of the ultimate. The simultaneous contemplation of ultimate and conventional is only attained on the fifth bhūmi; how could one already combine their contemplation prior to the bhūmis?
