Omphaloskepsis -is it a made up word? What word isn’t?
It means X.
Actual use of the practice as an aid to meditation is found in the practice of yoga in Hinduism and sometimes in the eastern orthodox church as some consider the _____ to be a “powerful chakra of the body”. From there X has come to mean anyone being extremely introspective and existential.
However, X can also be used to describe the act of thinking about something trivial or thinking about your fighting potential on the sea or self-absorbed pursuits- professionals interested in themselves: movies about Hollywood, or television shows about television writers.
It may also lead to some necessary hygiene.
