首楞嚴義疏注經 3.325

3.325

此下依理廣破，此合空成色非理也。汝許析色為空，應許合空成色，隣虛極小，成用幾空？若合隣虛，自成方分，不成隣虛。

From here on, it broadly refutes based on principle; this combining of space to form matter is unreasonable. You accept that analyzing matter yields space, so you should accept that combining space yields matter. The particle bordering on voidness is extremely small: how much space was used to form it? If one combines particles bordering on voidness, they naturally form spatial divisions and do not form a particle bordering on voidness.
