二、示處居家。「卜居」者，龜曰卜。古人移徙必卜吉而居之。「三界有二種」者，荊溪云：變易、分段也。「開合對四土」者，開變易、合分段。開變易者，離出有餘果報二土。合分段者，不分同居淨穢之殊。

Second, showing dwelling at home. Regarding "divining a dwelling," the turtle shell is called divination. When ancients relocated, they always divined an auspicious [site] and dwelt there. Regarding "there are two kinds of three realms," Jingxi says: "transformation [birth] and fragmented [birth]." Regarding "unfolding and combining to correlate with the four lands," it unfolds transformation [birth] and combines fragmented [birth]. Unfolding transformation [birth] separates the two lands of with-remainder and fruit-reward. Combining fragmented [birth] does not differentiate the distinction between pure and defiled in the co-dwelling [land].
