The ten levels of realization reached by Bodhisattvas on the paths of seeing, meditation and beyond learning. In some classifications additional levels are added. "These levels are sublime because they are far beyond ordinary beings." DICT.

Ground or level. In the Mahāyāna, the ten grounds of bodhisattva realization (so described from the point of view of post-meditation experience only) extend from the path of seeing through the path of meditation and culminate in the attainment of the path of no more learning, which is buddhahood. The first seven grounds are termed impure, because the defiled emotional consciousness (which, turning toward the ālaya, is what constantly conceives of "I") is still present in the mind of the yogi, and, even though not active, this results in the perception of a distinction between the observing mind and the object observed (gnyis snang). On the eighth ground, this defiled consciousness is removed, with the result that the strongest manifestations of this dualistic appearance are dissipated. On the ninth and tenth grounds, even the most subtle traces of this gradually cease. According to the Hīnayāna, there are eight grounds of realization. According to the Vajrayāna, there are thirteen grounds or more. [TPQ, 2010]
