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.
