瑜伽論記 1.139

1.139

解云：空一顯色之與逈色，約體是同，故是合說。對法中，空一顯色與逈色不同。所以然者？體雖是一，而約處別，是故別說。謂在上空現者，名空一顯色。若近下逈處現者，名為逈色。上觀見蘇迷盧山青、瑠璃影作虛空解，則就影色假立，空一顯色。

The explanation says: the color revealing empty space and the color of distant space are identical in terms of substance, so they are spoken of together. In the Abhidharmasamuccaya, the color revealing empty space and the color of distant space are not the same. Why is this? Although their substance is one, they are distinguished by location, and therefore spoken of separately. That which appears in the sky above is called the color revealing empty space. That which appears nearby in a distant place below is called the color of distant space. Looking up and seeing the shadow of the blue lapis lazuli of Mount Sumeru and taking it to be empty space, then the color revealing empty space is provisionally established based on shadow-matter.
