21.105

無色邊果一者，邊謂空處近分，近空處故，名無色邊。以空處近分起有漏道，能斷色界修惑盡故，唯得色愛盡一遍知果也。

"The fruit of the border of the formless is one": "border" refers to the access to the sphere of infinite space; being close to the sphere of space, it is called the border of the formless. Because one gives rise to the defiled path in the access to the sphere of space and is able to completely abandon the defilements of cultivation of the form realm, one attains only the single fruit of comprehensive knowledge of the exhaustion of attachment to form.
