第二約心破空有中，「世人說空名無色」等，舉他所立。「即心數」者，徵同心法。「若同心」下，徵為三世。「若三世」下，徵為四陰。「是故離」下，結成無空。

In the second, refuting the existence of space in terms of mind: "Worldly people say that space is called formless..." and so forth cites what the opponent posits. "Then it is a mental factor" interrogates it as being identical with mental dharmas. From "If it is identical with mind..." onward interrogates it as belonging to the three periods of time. From "If it belongs to the three periods of time..." onward interrogates it as belonging to the four aggregates. From "Therefore, apart from..." onward concludes that there is no space.
