唯識二十論述記 2.141

2.141

述曰：至者到也、得也、及也。體是一物，於一時中，若手執時，理不應有此處可得，彼處未得。今依此難，一切世間無一物者。所以者何？且如一筆，以手執時，有至、未至，如何成一？故知大乘諸眼等境，或可說一，總可至故，如手握珠；或可說多，至、未至故，如指捻珠。應立量云：汝宗世間無隔斷物無有一法有至、未至；執是一故；如手握珠。

Commentary: "Reaching" (至) means arriving (*dào*), attaining (*dé*), or extending to (*jí*). When its substance is one thing, at one and the same time, if grasped by the hand, it is logically impossible that this place is attained while that place is not yet attained. Now, according to this refutation, in the entire world there is no single thing. Why is this? Consider a single brush: when grasped by the hand, there is reaching and non-reaching; how could it be established as one? Therefore we know that in the Mahāyāna, the objects of the eye and the rest may either be said to be one because they can be reached as a whole, like grasping a pearl with the hand; or they may be said to be multiple because there is reaching and non-reaching, like rolling a pearl between the fingers. One should frame an inference: In your school, a worldly object without intervening breaks cannot have any single phenomenon that has reaching and non-reaching; because you hold it to be one; just like grasping a pearl with the hand.
