In philosophy, Ultimate Reality is the absolute nature of all things. It is different from ordinary reality, which is considered a product of the individual consciousmind. Ultimate Reality is independent of observation.
An Ultimate Reality is generally alluded to by non-theistic religions where theistic religions would speak of divinity.
The existence of an Ultimate Reality is debated. MetaphysicalSubjectivism says that perception alone creates reality, and there is no underlying, true, reality that exists independent of perception. One can also hold that it is consciousness rather than perception that creates reality. However, Ultimate Reality theorists hold that there must be an objectivetruth for which to base one's perception, and that the difference in perception from person to person, reality tunnel to reality tunnel, is not due to a lacking objectivity, but rather can be attributed to the complexities that encompass the perception of one's environment, as well as differing environments between all.
The real distinction is between those who adapt their purposes to reality and those who seek to mold reality in the light of their purposes.
Reality, according to Mahayana Buddhism, has three levels of perception, known also as the three bodies (trikaya) of Buddha: nirmanakaya, the physical body of the founder, that is subject to change; sambhogakaya, the body of the boddhisattvas; and dharmakaya, the ultimate nature of all things.
To see the reality of dukkha, as it is one has to see it for oneself, and the way to this realisation is through the practice of meditation, through listening to the teaching on the dhamma and by the exercise of wisdom.
