𝌝
U+1D31D "𝌝" Tetragram for Joy is a symbol from the Tai Xuan Jing, an ancient Chinese divination text created by the philosopher Yang Xiong, which extends the concept of the I Ching's hexagrams into a system of 81 tetragrams. This specific tetragram represents joy, often associated with lightness, liberation, and positive emotional release, and it is used in the context of metaphysical exploration to denote a state of harmony and freedom from constraint. Part of the Unicode Tai Xuan Jing Symbols block, the character appears as a stylized monogram composed of three horizontal lines, with a broken line at the top, a solid line in the middle, and a broken line at the bottom, encoding a traditional numerical and philosophical meaning.
