Heaven medial vowels, Earth vowels, Human vowels

    Vowels are divided into three categories. Heaven vowels
    include ㆍ, Earth vowels include ㅡ, and the combination of
    Earth (ㅡ) and Heaven (ㆍ) forms ㅗ ㅜ ㅛ ㅠ. Human
    Vowels represent humanity, symbolized by ㅣ, and the
    combination of Human (ㅣ) with Heaven (ㆍ) creates ㅏ ㅓ
    ㅑㅕ. This tripartite division of vowels is used to explain
    their placement. Heaven vowels and Earth vowels are
    positioned below the initial consonant, while Human vowels
    are placed to the right of the initial consonant.


    Ggeut, OnGgeut, SeOnGgeut (끝, 온끝, 세온끝)

    These are Korean expressions representing Mugeuk(infinite
    ultimate), Taeguk(supreme ultimate), and
    Samtaeguk(threefold supreme ultimate).
    Ggeut symbolizes Mugeuk, the infinite and boundless origin
    before any division. It is described as the "Empty End,"
    representing the limitless, unbounded state before the
    creation of Taeguk. The term Teonggeut (Empty End) is a
    combination of 텅 teong (emptiness) and 끝 Ggeut
    (extreme), signifying a "fundamental state of infinite
    emptiness." It is expressed as either Geut or TeonGgeut.
