[Summary: This is a continuation of the prior script titled "Symbiont." Features and properties of the organism are compared with those of water, to make the symbiont's presence easier to discern. Following that, we explore the idea that your (repeated) submission to it could allow you to achieve a symbiosis with the black fluid...such that it remains with you all the time.] This post is part of the black fluid series, and is meant to accompany the prior. As before, having a glass of water nearby can be helpful. Unlike before, it will not be necessary.
