3.344

量有二義：一者土果形量，謂一一方四百萬億那由他土果形量；二者因量，謂無漏善根生，非有漏善根起也。

Measure has two meanings: first, the physical measure of the fruition of the land, meaning the physical measure of the fruition of the land being four million nayutas [of leagues] in each direction; second, the measure of the cause, meaning being produced from uncorrupted wholesome roots, not arising from corruptible wholesome roots.
