Iso-meditation

Cheongsu is where the practice of iso-meditation is carried out. Practitioners dress in a high-pressure diving suit and exit from the deepest level of the underwater complexes, on the abyssal plain itself. They then walk 250 meters from the facility, and then douse the suit’s internal lights and cut communication to the facility. The absence of terrestrial stimulation and the presence of marine bioluminesce and auditory cues create highly desirable depersonalization and alienation suitable to mediation exercises.

It is also used as a form of training for Jeobseoni Dogsuli spaceborne special forces. They learn to accept the sheer darkness and isolation to attain absolute calm, and put themselves in this state of mind while dropping from orbit or in combat. This is what shapes the Dogsuli into the lone wolf special forces they are, with deadly precision with their weapons and weeks-long solo activities in the wilderness behind enemy lines.

Notably, Orbital Divers now also receive this training, but carry it out in groups to improve camaraderie as well.
