Banned in some polities and commonly confused with some toposophic transcension devices by laybeings, the transcension machine is a nanotech pill used by those who have grown tired of the mundane life and who wish to transcend to a spiritual plane or other existence, or to simply die.
When activated, a transcension machine initiates two parallel programs. One works to slowly and painlessly deactivate bodily functions. The other induces the user's mind into a state of awake-dreaming, bringing good sensations to the euthanasing being. This state does not impair the perceptions of the being in any way other than as a result of sensory degradation resulting from the deactivation of bodily systems caused by the device.
Modern transcension machines have been optimized such that the shutdown process can be fully reversed even when more than 50% of it has been completed, through a mental command from the user.
Transcend-Ascend - Text by M. Alan Kazlev One who transcends to one toposophic, then ascends to the next. For example an intelligence may transcend to SI:1, leaving behind everything of itself that was of SI:<1. Then e may ascend to S2, retaining eir SI:1 nature but adding an S2 superstructure on top of the SI:1 nature. Contrast ascend-transcend. Often however the dividing lines are not this well defined.
Transcendent Being - Text by M. Alan Kazlev An entity that is distinct from physical existence, whether considered ontologically, as a supernatural or supraphysical being, or soteriologically, as a being that is no longer a part of embodied existence or samsara. The existence of a transcendent being or beings (e.g. God, Buddhas, etc.) is central to many religious memeticities, but denied by physicalist memeticities.
Transcension Prediction - Text by Anders Sandberg and M. Alan Kazlev Given the huge population of the civilized galaxy, and the fact that ascensions and transcensions are moderately common and have been going on for thousands of years, many polities and civilizations have developed some fairly reliable methods for predicting the onset of one of these events. Often this is comparable to pre- and post-singularity efforts at predicting the weather (and a large transcendence event does indeed share some conceptual characteristics with a force of nature to those watching from outside at a lower S level).
