八識規矩補註 1.46

1.46

遠行乃第七地也。此識於七地已前漏無漏間雜而生，以未常在觀門故；至此地後而純無漏，以俱生二障永不現行恒在觀門故，生空乃恒，法空猶間。又云：十地中前五地，有相觀多無相觀少，第六地，有相觀少無相觀多，至七地中，純無相觀也。

The Far-Reaching Ground is the seventh bhūmi. Prior to the seventh bhūmi, this consciousness arises in an intermingling of the tainted and taintless, because it is not constantly within the gateway of contemplation. After reaching this bhūmi, it is purely taintless, because the two innate obscurations never manifest actively and it is constantly within the gateway of contemplation; emptiness of the person is constant, while emptiness of phenomena is still intermittent. Furthermore, it is said: among the ten bhūmis, the first five bhūmis have much contemplation of marks and little markless contemplation; the sixth bhūmi has little contemplation of marks and much markless contemplation; upon reaching the seventh bhūmi, it is purely markless contemplation.
