Righ Thought means liberating oneself from the threefold world. Such liberation means the Bright Light of Nirvana Wisdom, by completely freeing oneself from the three poisons of mind and the eighth consciousness Alaya, where the three poisons are the ‘Time’ of the threefold world of desire, form and formlessness, and the Alaya consciousness is the ‘Space(Timelessness).’ The release of oneself from the threefold world is signified by the Perfect Enlightenment being reflected in the Zen Wood Old Mirror.
The Perfect Enlightenment thus has come stays in the Buddha-heart, the Nirvana Palace of Divine Equanimity, helping all sentient beings enter Nirvana and thus attain Buddhahood, which means the Anuttara-Samyak-Sambodhi. As such, the ten names of the Perfect Enlightenment all are represented by the sunlight of the dawn, and the sunlight of the dawn signifies the Sakyamuni Buddha, denoting the place of living where all activities of reality are unfolded as manifestations of enlightenment.
The place of enlightened living is expressed as ‘Blue Mountain and White Cloud, the Sweet-Dew Tea.’ The Blue Mountain signifies the Blue Sky, which means the Ocean Seal Samadhi. The White Cloud brings forth the faith that a smoke rising from a distant mountain certainly suggests there should be a fire in the mountain, which means the world of enlightenment.
